Mirror of snapetech-org/seerrng#630 (the Lumen part; the server changes live upstream only).

Lumen

• Book pages judged ownership from the aggregate media status, so owning the audiobook showed the ebook as owned ("Read in Audiobookshelf", no Request ebook). Ownership is per format, and a format with its own pending/approved request shows as requested instead of offering Request again.

Server (upstream only, summarized)

• The book library lists every owned book (identifier lookups were capped at 200, #625).
• Requests finalize from known files while Chaptarr metadata lookups fail, and lookups back off.
• Narrator requests complete after import (Hardcover edition ids compared across hc:N / hc:edition:N-audiobook).
• Duplicate Chaptarr records pool their file evidence; a deleted tracked book counts as gone; audiobook search falls back to the known catalogue; padded Bookshelf ids work.

Tests
