Backport #30309 by @silverwind
Fix the action issue in https://github.com/go-gitea/gitea/issues/30303,
specifically:
- Use opaque step header hover background to avoid transparency issue
- Un-sticky the `action-view-left` on mobile, it would otherwise overlap
into right view
- Improve commit summary, let it wrap
- Fix and comment z-indexes
- Tweak width for run-list-item-right so it wastes less space on desktop
- Synced latest changes to console colors from dark to light theme
