Subject: Diff improvements (#23553)

- Avoid flash of wrong tree toggle icon on page load by setting icon
based on sync state
- Avoid "pop-in" of tree on page load by leaving space based on sync
state
- Use the same border/box-shadow combo used on comment `:target` also
for file `:target`.
- Refactor `DiffFileTree.vue` to use `toggleElem` instead of hardcoded
class name.
- Left-align inline comment boxes and make them fit the same amount of
markup content on a line as GitHub.
- Fix height of `diff-file-list`

Fixes: https://github.com/go-gitea/gitea/issues/23593

(Yes I'm aware the border-radius in bottom corners is suboptimal, but
this would be notorously hard to fix without relying on `overflow:
hidden`).
