fix(photos): paginated search with infinite scroll (#613)

Browse Source 
Replace bulk-loading all Immich photos (up to 20k) with paginated
search: 50 photos per page, automatic infinite scroll via
IntersectionObserver. Prevents server blocking on large libraries.

- Backend: searchPhotos accepts page/size params, returns hasMore
- Frontend: loads 50 at a time, appends on scroll
- AbortController cancels in-flight requests on tab switch
