Apparently tables have certain user-agent styles that center inside
`<th>` etc. Restored the original fomantic rules for these.

Fix regression from https://github.com/go-gitea/gitea/pull/30033

These buttons had lost their border because `.ui.header` sets `none` but
`.ui.menu` has it, after the migration, the order of styles changed and
header won. I see no reason why those have the `header` class in first
place, besides for semantic meaning.

Fix regression from https://github.com/go-gitea/gitea/pull/30014. The
rule was to broad and affecting things like `primary` button
unintentionally.

Fix #29997

Help #29999, or its tests cannot pass.

Also, add some comments to clarify the usage of `TxContext`.

I don't check all usages of `TxContext` because there are too many
(almost 140+). It's a better idea to replace them with `WithTx` instead
of checking them one by one. However, that may be another refactoring
PR.

We have to define this one in helpers.css because tailwind only
generates a single class but certain things rely on this being
double-class. Command ran:

Another CSS-only module. Also, I re-ordered the imports based on
[original fomantic
order](https://github.com/fomantic/Fomantic-UI/blob/2.8.7/src/semantic.less).

This will conclude the refactor of 1:1 class replacements to tailwind,
except `gt-hidden`. Commands ran:

```bash
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-0#tw-$1$2-0#g'   {web_src/js,templates,routers,services}/**/*
perl -p -i -e 's#gt-(p|m)([lrtbxy])?-1#tw-$1$2-0.5#g' {web_src/js,templates,routers,services}/**/*

By using git's ability, end users (especially small instance users) do
not need to enable the indexer, they could also benefit from the code

Small CSS module. There was a ordering conflict between `.ui.menu` and

base.

Migrate `gt-font-*` to `tw-text-*` All tailwind-original class names are
also available and render like they would with 16px root font size.

We currently have root font size at 14px, but I would like to eventually
migrate us to 16px so that the tailwind docs apply to us unchangend and
because 16px is the recommended root font size for web pages in general.
Also the number 16 is much better dividable than 14 so will result in
more integers.

These should be all simple inline styles that were left in the
templates.
