chore: migrate all FA icons to Lucide (@lucide/svelte)

- Replaced all active FontAwesome <span class="fas fa-*"> icons with
  Lucide components across 145 files (excluding /idaa/ which is intentional)
- Fixed merge script bug: consolidated lucide-svelte imports into @lucide/svelte
- Replaced dynamic toggle patterns (fa-toggle-on/off) with ToggleRight/ToggleLeft
- Replaced fa-eye/fa-eye-slash with Eye/EyeOff
- Replaced fa-bug/fa-bug-slash with Bug/BugOff
- Replaced fa-sync fa-spin with RefreshCw + animate-spin
- Replaced fa-microchip with Cpu
- Fixed {@const} placement in element_manage_event_file_li.svelte
- Removed obsolete CSS hover rules for .unlock_icon/.lock_icon
- svelte-check: 0 errors, 0 warnings
