diag(ci/release): dump provisioning-profile dirs around the iOS archive

iOS manual signing fails 'No profile matching Punktfunk App Store Distribution'
despite the profile being installed (content verified: right name/team/iOS/app-id).
The profile is in ~/Library/MobileDevice but Xcode 26 reads
~/Library/Developer/Xcode/UserData/Provisioning Profiles, which is empty. Print
both dirs before the archive and again at failure to confirm whether Xcode
regenerates/prunes the UserData copy during the build.
