feat: wire NFO repair scan into app startup lifespan

docs/CHANGELOG.md

@@ -62,6 +62,10 @@ This changelog follows [Keep a Changelog](https://keepachangelog.com/) principle
   either queues the series for background reload (when a `background_loader` is
   provided) or calls `NfoRepairService.repair_series()` directly. Skips
   gracefully when `tmdb_api_key` or `anime_directory` is not configured.
+- **NFO repair wired into startup lifespan (`src/server/fastapi_app.py`)**:
+  `perform_nfo_repair_scan(background_loader)` is called at the end of the
+  FastAPI lifespan startup, after `perform_media_scan_if_needed`, ensuring
+  every existing series NFO is checked and repaired on each server start.
