Add support for per-request custom search terms and an admin retry-download flow.
- DB/schema: add custom_search_terms column via Prisma migration and schema update.
- Admin UI: new AdjustSearchTermsModal component and UI badges to show custom search status; RequestActionsDropdown and RecentRequestsTable updated to surface adjust/retry actions.
- API: new PATCH /api/admin/requests/[id]/search-terms to set/clear custom terms (optionally trigger a new search) and new POST /api/admin/requests/[id]/retry-download to resume monitoring or re-add downloads using DownloadHistory metadata.
- Behavior: interactive search now prefers customSearchTerms when present; manual import exposes cleanupSource option to organize job; admin requests listing returns downloadAttempts and customSearchTerms.
- UX: add SectionToolbar, LoadMoreBar and HideAvailableToggle components and wire hide-available preference across home, search, author and series pages; authors/series endpoints/page handlers gain pagination metadata.
- Misc: add connection-errors util and update related processors/services and tests to cover the new flows.
These changes enable admins to override search terms per request, trigger searches from the admin UI, and retry failed downloads more robustly.
Introduce full authors browsing/detail feature and enhance notifications to support type-specific titles.
- Add server APIs: authors search, author detail, and author books routes (audnexus integration) that require auth and enrich results with library matches.
- Add frontend pages/components: /authors listing and /authors/[asin] detail pages; AuthorCard, AuthorGrid, AuthorDetailCard, SimilarAuthorsRow, and related skeletons.
- Add hook and integration stubs: new useAuthors hook and audnexus-authors integration; update audible service to expose audibleBaseUrl.
- Update AudiobookDetailsModal to use audibleBaseUrl and link author names to author detail pages.
- Add header navigation link to Authors.
- Notifications: extend docs and code to include requestType (audiobook|ebook), add getEventTitle/getEventMeta helpers, update queue signature and providers/processors/tests to pass/handle requestType so titles can be resolved per request type.
- Misc: job queue, processors, provider tests and notification tests updated to reflect new behavior.
This change enables browsing authors and provides type-aware notification titles without per-provider changes.
