refactor(sql): use sqlc.narg() pattern for optional library_id in all library-filtered queries

Convert 12 SQL queries to use sqlc.narg('library_id') instead of
direct @library_id parameters. This allows passing a NULL/invalid
pgtype.UUID to mean "no library filter" (i.e., All Libraries),
making the SQL layer correctly handle the optional filter via:
  (sqlc.narg('library_id')::uuid IS NULL
   OR mi.library_id = sqlc.narg('library_id')::uuid)

Also remove the library_id filter from GetSeriesBooks entirely —
a series is a series regardless of library.

Queries affected:
- GetDashboardSections, GetRecentlyAdded, GetInProgress
- GetHighestRated, GetMostRead, GetAbandonedBooks
- GetLeastRead, GetBooksByTag, GetCollectionItemsForDashboard
- SearchMediaItemsUnified, GetSeriesCardsData

Generated code (queries.sql.go, querier.go) regenerated via sqlc.
