Optimize database indexes and clean up schema (#1603)

Browse source 
* Update `excluded_scanlators` index to a composite index on `manga_id` and `scanlator`.
* Convert `idx_history_last_read` into a partial index for entries where `last_read > 0`.
* Remove redundant `idx_manga_sync_manga_id` index.
* Remove unused `last_modified_at` column and its associated trigger from `mangas_categories`.
* Sync migration files with schema changes.
