feat(audiobooks): wire Phase 1 close-out stores + mount routes

Wires RSSFeedStore into BuildABSHandler. Mounts the ten new
authenticated routes (stats x3 + author x1 + series x1 + continue x2
+ feeds-auth x3) under both /abs/api and /api inside bearerAuth.
Mounts the three public RSS routes (.xml + slug + /file/{ino}) in
the unauth public block. handleAuthorImage wired to CoverResolver.
