Update frontend route handlers for /collections and /collections/:id
to fetch user-visible libraries and pass libData + currentLibraryID
to templates, enabling the library switcher dropdown.
/collections handler:
- Fetch GetUserVisibleLibraries for the current user
- Derive currentLibraryID from query param, falling back to first library
- Convert to []templates.LibraryData and pass to Collection template
/collections/:id handler:
- Fetch GetUserVisibleLibraries alongside existing book fetching
- Pass libData to CollectionDetail template alongside existing libraryID
- Refactored to use shared libraryID variable across system/user paths
