Fix anipy fallback episode numbering

Use the queued episode spec when finalizing anipy-cli fallback TV downloads so retries keep the requested episode numbers instead of being renumbered from 1, and update tests plus release docs for the fix.

 # Changelog
 
+## 0.47.1 - 2026-07-09
+
+- Fixed `anipy-cli` fallback renaming for queued TV downloads so retried jobs now keep the requested episode numbers from the queue, avoiding cases like a retried `S02E11` being renamed as `S02E01`.
+
 ## 0.47.0 - 2026-07-09
 
 - Added an optional `anipy-cli` fallback toggle on the Config page so failed `ani-cli` queue jobs can automatically retry once with `anipy-cli`.
