Advance existing requests from Interactive Search

Pass requestId and requestedByUserId through request list and card components and into AudiobookDetailsModal. Add ADVANCEABLE_FROM_INTERACTIVE_SEARCH constant and logic so the Interactive Search modal routes to /api/requests/[id]/select-torrent for own/admin advanceable requests instead of creating a new request. Fix download-token usage to use the in-flight request id, extend Audiobook type with requestedByUserId, and add tests covering advance-vs-create routing and select-torrent behavior.
