refactor: Add Alpine.js registration to existing TypeScript modules

Added Alpine.global() registration to enable template access to functions:

- admin.ts: Added Alpine for scan, stats, and settings functions
- api-explorer.ts: Already had Alpine (kept as is)
- bookshelf.ts: Added Alpine for library/bookshelf interactions
- collections.ts: Added Alpine for collection management
- conflicts.ts: Added Alpine for conflict resolution
- device-management.ts: Added Alpine with event delegation for dynamic content
- header.ts: Added Alpine for theme dropdown and user menu
- library.ts: Added Alpine registrations
- linking.ts: Added Alpine registrations
- queue.ts: Added Alpine for queue operations
- search.ts: Added Alpine registrations
- themeDropdown.ts: Added Alpine for theme switching

Each module now exports functions both traditionally and via Alpine.global() for template access.
