feat(core): add pagination to explore, search, person, and library endpoints

Convert trending, search, people.detail, and dashboard.library to page-based responses (`page` / `totalPages`) so clients can load results incrementally.

Update `@sofa/core` discovery and person services to accept a `page` / `limit` input and slice results accordingly. Add a new DB migration to persist the data needed to back paginated filmography queries.

On the web, introduce a `useInfiniteScroll` hook and wire up `useInfiniteQuery` in the explore, person detail, and filterable title row components with an intersection-observer sentinel. On native, switch the same screens from `useQuery` to `useInfiniteQuery` with `onEndReached` / `ListFooterComponent` loading indicators. Also replace remaining `FlatList` usages with `FlashList` in the home and title detail screens.
