Best quality format, password UX, mobile columns

Best quality format:
- Synthetic 'bestvideo+bestaudio/best' entry added at top of format
  list when the best separate video stream exceeds the best pre-muxed
  format. Shows as 'Best quality (1920x1080)' in Video+Audio group.
- YouTube typically only has 360p pre-muxed but 1080p+ as separate
  streams — users can now select full quality with auto-merge.
- Only appears when there's actually a quality advantage vs pre-muxed.

Password change UX:
- Enter key on confirm password field submits the change
- Auto-logout 1.5s after successful password change
- User sees '✓ Password changed' before being redirected home

Mobile table:
- Status column hidden on mobile (<640px) alongside Progress
- Only Name + Actions columns shown — clean two-column layout
- Removed mobile-specific status badge font tweaks (column gone)
