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.

Single-scroll layout with two _SectionHeader-anchored blocks. Users
rows tap into AdminUserEditSheet. Invites row shows token (monospace)
with copy button, optional note, and a redeemed badge if applicable.
"Generate invite" opens a small dialog with an optional note field
(server hardcodes 24h TTL — admins can't customise expiry). On
success the new token is shown in a copy-once result dialog.
