Confirmed via curl from a clean IP: Apple's iTunes /search returns 403 (blocked
server-side, likely datacenter-IP anti-scraping) while /lookup?id= still returns 200.
So the Erkunden Apple search fails through no fault of ours.
- Charts: the "most-played" RSS (rss.applemarketingtools.com) was fetched directly
from the browser and hit CORS; proxy it via /api/itunes-charts/:kind.
- Error visibility: itunesSearch records the last outcome (HTTP status / network);
the global-search view now shows "Apple-Suche gerade nicht verfügbar" with the
reason (403 = Apple blocks the API, not you) instead of a blank "no results".
- iTunes proxy now forwards the upstream status code instead of always 200.
Deezer (free, no key, ~50 req/5s) is the planned search fallback; MusicBrainz is too
rate-limited (1/s) for interactive search.
