- remove the redundant wishlist-service injection from the runtime wrappers
- keep the package owning its own singleton service access
- simplify the route runtime API and update the wishlist tests to match
- add module-level loggers for the wishlist package instead of threading the web server logger through runtime objects
- default wishlist helper runtimes and cleanup helpers to their package logger while still allowing test overrides
- keep web_server.py as a thin caller that no longer injects its logger into wishlist flows
- extract the remaining wishlist endpoint behavior from web_server.py into core/wishlist/routes.py
- keep web_server.py as a thin Flask adapter around the new route helpers
- add tests that cover wishlist counts, stats, track listing, clear/remove flows, cycle updates, and album-track adds
