Mechanical sweep across 30 files: every Material Icons.* replaced with
the signed-off Lucide equivalent + a flutter_lucide import per file.
Zero Material Icons.* remain in lib/; no unused imports.
Judgment-call mappings: album->disc_3, library_music->library_big,
playlist_play->list_video, graphic_eq->audio_lines,
system_update->download, restore->archive_restore,
download_done->circle_check_big.
track_actions_sheet like menu row: collapsed `liked ? favorite :
favorite_border` to a single LucideIcons.heart (the row's Like/Unlike
text label conveys state). Icon-only LikeButton + the notification keep
the filled-vs-outline shape per the design decision.

AdminUserRow shows username + admin/auto-approve badges; tap opens
AdminUserEditSheet bottom sheet.
Edit sheet: SwitchListTile pair for is_admin and auto_approve_requests
(both surface server errors via SnackBar, including the last-admin
guard). Reset password takes a typed-input dialog (>=8 chars enforced
client-side; admin supplies the new password). Delete routes through
TypedConfirmSheet ("DELETE") and pops the sheet on success.
