This PR introduces a new UI element type for Gitea called `flex-item`.
It consists of a horizontal card with a leading, main and trailing part:


![grafik](https://github.com/go-gitea/gitea/assets/47871822/395dd3f3-3906-4481-8f65-be6ac0acbe03)

The idea behind it is that in Gitea UI, we have many cases where we use
this kind of layout, but it is achieved in many different ways:
  - grid layout
  - `.ui.list` with additional hacky flexbox
- `.ui.key.list` - looks to me like a style set originally created for
ssh/gpg key list, was used in many other places
  - `.issue.list` - created for issue cards, used in many other places
  - ...

This new style is based on `.issue.list`, specifically the refactoring
of it done in #25750.

In this PR, the new element is introduced and lots of templates are
being refactored to use that style. This allows to remove a lot of
page-specific css, makes many of the elements responsive or simply
provides a cleaner/better-looking way to present information.

A devtest section with the new style is also available.

Hi!
This pull request adds support for downloading raw task logs for Gitea
Actions, similar to Github Actions
It looks like the following:

![image](https://user-images.githubusercontent.com/945339/235376746-405d5019-710b-468b-8113-9e82eab8e752.png)

Part of #25042

1. Added actor and status dropdowns first in case something is offtrack
and PR is too large.

2. Also added "No results matched." and "The workflow has no runs yet.",
and "No results matched." will show if there is no filter results and
there is no workflows (with [reference to github
action](https://github.com/go-gitea/gitea/actions/workflows/files-changed.yml?query=actor%3AGiteaBot))

Demo:


https://github.com/go-gitea/gitea/assets/17645053/6e76292c-4c1f-450d-8b48-99944cfc920c


TODOs:

- [x] Get available status (same as those in `aggregateJobStatus`)
instead of getting from database
- [x] Use `JOIN` to get actors, actors order by name
- [x] Make self on top

Main changes:

- Moved the icon into `action-item-main`, and make it `position:
absolute` to allow add margin it to align with `issue-item-top-row`.
- Adjusted padding and color of texts.

- The timestamp shows local time and is parsed by `date.toLocaleString`;
- "show seconds" and "show timestamps" are mutually exclusive, and they
can be both hidden.

Implement action artifacts server api.

This change is used for supporting
https://github.com/actions/upload-artifact and
https://github.com/actions/download-artifact in gitea actions. It can
run sample workflow from doc
https://docs.github.com/en/actions/using-workflows/storing-workflow-data-as-artifacts.
The api design is inspired by
https://github.com/nektos/act/blob/master/pkg/artifacts/server.go and
includes some changes from gitea internal structs and methods.

Actions artifacts contains two parts:

- Gitea server api and storage (this pr implement basic design without
some complex cases supports)
- Runner communicate with gitea server api (in comming)

Old pr https://github.com/go-gitea/gitea/pull/22345 is outdated after
actions merged. I create new pr from main branch.

Add artifacts list in actions workflow page.

We should just show all runs. This removes the filtering altogether.

Fixes https://github.com/go-gitea/gitea/issues/10410.
This PR removes around 120kB of CSS.

Partial regression of #24393, not only regression, but broken for long
time, 24393 didn't really improve it but used wrong `overflow: scroll`.

Actually, that "ui secondary filter menu labels" shouldn't be set as
scrollable (I missed that at that time), the problem is: if a "ui menu"
has "dropdown" items, then it should not be scrollable. Otherwise the
dropdown menu can't be shown correctly.

And there are more problems:

* The "issue-filters" shouldn't be used anywhere else (copying&pasting
problem again ....)
* There is also an "issue-actions" container, it should also be fixed.
* There are similar problems on the milestone page.
* The old comment in code: "grid column" doesn't work well.

The major changes of this PR are: use "flex: 1" instead of "ui grid
column".

After this PR, not 100% perfect but much better than before.

- Make search bar dynamic full width via flexbox
- Make all buttons `small` so font size is the same for all elements in
the header
- Remove primary color from search field, add SVG icon like on Code tab
- Fix button vertical padding being enlarged by SVG icons

Close #24302 
Part of #24229, Follows #24246
This PR focused on CSS style fine-tune, main changes:

1. Give `.ui.ui.ui.container` a width of `1280px` with a max-width of
`calc(100vw - 64px)`, so the main contents looks better on large
devices.

2. Share styles for table elements in all levels settings pages to fix
overflow of runners table on mobile and for consistency (The headers on
mobile can be further improved, but haven't found a proper way yet).

3. Use [stackable
grid](https://fomantic-ui.com/collections/grid.html#stackable) and
[device column width](https://fomantic-ui.com/examples/responsive.html)
for responsiveness for some pages (repo/org collaborators settings

Maybe we can also add online runner check? e.g. : Target runner is
offline.

These icons are the same now:

In this PR, didn't use `ActionRunStatus.vue` because the mounting of the
component will cause flash of the icons like below:

https://user-images.githubusercontent.com/17645053/232682646-713202dc-9023-4b9c-a849-c3a1ae6dd155.mov

Instead, modified and used `status.tmpl` to make it the same as
`ActionRunStatus.vue` to avoid the ui flash (Welcomed to show how to use
`ActionRunStatus.vue` without flashing if there is a way).
Added comments to both of them for reminding synchronization of these
two files.

Follow:
* #23574
* Remove all ".tooltip[data-content=...]"

Major changes:

* Remove "tooltip" class, use "[data-tooltip-content=...]" instead of
".tooltip[data-content=...]"

Tooltip -> Tippy Tooltip refactoring
* Rename reaction attribute from `data-content` to
`data-reaction-content`
* Add comments for some `data-content`: `{{/* used by the form */}}`
* Remove empty "ui" class

1 Right now on actions page, the action list will not be aligned if
commit message is long. In this PR, the changes are:
- The branch tag is moved to bottom row
- Width percentage is given to make them aligned
- Show "..." if commit is longer than two lines.
- Align the status icon with the commit message with baseline

Strings are passed to the pager

The action run title has a blank. This PR removes it.

As discussed in #22847 the helpers in helpers.less need to have a
separate prefix as they are causing conflicts with fomantic styles

This will allow us to have the `.gt-hidden { display:none !important; }`
style that is needed to for the reverted PR.

Of note in doing this I have noticed that there was already a conflict
with at least one chroma style which this PR now avoids.

I've also added in the `gt-hidden` style that matches the tailwind one
and switched the code that needed it to use that.

I haven't tested `runs_list.tmpl` but I think it could be right.

After this PR, besides the `<meta .. HTMLURL>` in html head, the only
explicit HTMLURL usage is in `pull_merge_instruction.tmpl`, which
doesn't affect users too much and it's difficult to fix at the moment.

There are still many usages of `AppUrl` in the templates (eg: the
package help manual), they are similar problems as the HTMLURL in
pull_merge_instruction, and they might be fixed together in the future.

Diff without space:
https://github.com/go-gitea/gitea/pull/22831/files?diff=unified&w=1

If triggered by PR, the ref should be `pull/<index>/head` instead of
`repo.DefaultBranch`.

And improve UI:

### Summary

The target of this PR is to bring a basic implementation of "Actions",
an internal CI/CD system of Gitea. That means even though it has been
merged, the state of the feature is **EXPERIMENTAL**, and please note
that:

- It is disabled by default;
- It shouldn't be used in a production environment currently;
- It shouldn't be used in a public Gitea instance currently;
- Breaking changes may be made before it's stable.

**Please comment on #13539 if you have any different product design
ideas**, all decisions reached there will be adopted here. But in this
PR, we don't talk about **naming, feature-creep or alternatives**.

### ⚠️ Breaking

`gitea-actions` will become a reserved user name. If a user with the
name already exists in the database, it is recommended to rename it.

### How to try it

<details>

#### 1. Start Gitea

Clone this branch and [install from
source](https://docs.gitea.io/en-us/install-from-source).

Add additional configurations in `app.ini` to enable Actions:

```ini
[actions]
ENABLED = true
```

Start it.

If all is well, you'll see the management page of runners:

#### 2. Start runner

Clone the [act_runner](https://gitea.com/gitea/act_runner), and follow
the
[README](https://gitea.com/gitea/act_runner/src/branch/main/README.md)
to start it.

If all is well, you'll see a new runner has been added:

#### 3. Enable actions for a repo

Create a new repo or open an existing one, check the `Actions` checkbox
in settings and submit.

<img width="1792" alt="image"
src="https://user-images.githubusercontent.com/9418365/205879705-53e09208-73c0-4b3e-a123-2dcf9aba4b9c.png">

#### 4. Upload workflow files

Upload some workflow files to `.gitea/workflows/xxx.yaml`, you can
follow the [quickstart](https://docs.github.com/en/actions/quickstart)
of GitHub Actions. Yes, Gitea Actions is compatible with GitHub Actions
in most cases, you can use the same demo:

```yaml
name: GitHub Actions Demo
run-name: ${{ github.actor }} is testing out GitHub Actions 🚀
on: [push]
jobs:
  Explore-GitHub-Actions:
    runs-on: ubuntu-latest
    steps:
      - run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event."
      - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!"
      - run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}."
      - name: Check out repository code
        uses: actions/checkout@v3
      - run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner."
      - run: echo "🖥️ The workflow is now ready to test your code on the runner."
      - name: List files in the repository
        run: |
          ls ${{ github.workspace }}
      - run: echo "🍏 This job's status is ${{ job.status }}."
```

If all is well, you'll see a new run in `Actions` tab:

<img width="1792" alt="image"
src="https://user-images.githubusercontent.com/9418365/205884473-79a874bc-171b-4aaf-acd5-0241a45c3b53.png">

#### 5. Check the logs of jobs

Click a run and you'll see the logs:

<img width="1792" alt="image"
src="https://user-images.githubusercontent.com/9418365/205884800-994b0374-67f7-48ff-be9a-4c53f3141547.png">

#### 6. Go on

You can try more examples in [the
documents](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions)
of GitHub Actions, then you might find a lot of bugs.

Come on, PRs are welcome.
