- events/[event_id]/+page.svelte: converted JS icon strings to Lucide component refs
  (Presentation, Plane, IdCard, Contact) — rendered via <mod.icon size="2rem" />
- +page.svelte: hover:variant-outline-warning → hover:preset-outlined-warning (×2)
- migrate_fa_to_lucide.py: added 18 new icon mappings
  (ArrowLeft/Right, Ban, Broom→Trash2, calendar-alt, Database, DoorOpen, Download,
   exchange-alt, file-image, lock, magic→Sparkles, print, sticky-note, sync, tag,
   trash, user-ninja/tie→UserRound, video)
