fix(ci): recreate CDN storage zone in EU (DE) region

Storage zone was accidentally created in NY. Recreated as
'coolify-update' in DE (Falkenstein) to keep update artifacts
in EU jurisdiction, consistent with Bunny.net data sovereignty
justification. Updated storage zone name, pull zone ID, and
reverted storage endpoint to default (storage.bunnycdn.com).
