Add ebook-sidecar APIs and UI integration

Introduce ebook-sidecar support: add new API routes for ebook workflows (ebook-status, fetch-ebook, interactive-search-ebook, select-ebook) that handle searching, selection, request creation, approval, and download routing (Anna's Archive direct downloads vs indexer downloads).

Update admin approval flow to understand request.type (audiobook | ebook), handle pre-selected ebook torrents (including special handling for Anna's Archive with direct download jobs and download history), and enqueue ebook-specific search/download jobs.

Frontend changes: show request type badge in admin pending approvals and augment AudiobookDetailsModal to query ebook status, start fetch/interactive ebook searches, and surface toast notifications. Also include new request lifecycle handling (retryable/active statuses, approval logic, creating audiobook records for Plex-imported books) and ranking/normalization logic for interactive ebook search results.

Other: various plumbing to integrate config checks, job queue calls, and download history storage for ebook downloads.
