Various code view improvements (go-gitea#30014)

1. Restore missing styles for message close icon
2. Move `code-line-button` so that it does not go off-screen on small
viewports
3. Make `code-line-button` look and behave like other buttons
4. Make `code-line-button` work in blame
5. Make the active selection span the whole line, not just the code part
6. Tweak colors, make dark theme code bg darker, make line numbers same
color in diff and file view.
7. Move code background to parent, fixing border radius and other
problems
8. Enable code wrap in blame
9. Improve blame responsiveness
10. Remove `--color-code-sidebar-bg` in blame, now it uses same
background as code
11. Rename `--color-active-line` to `--color-highlight-bg`
12. Add `--color-highlight-bg`
13. Fix button group borders on hover and border-right on last button.
