fix(ci): use Release + archive/export for Firebase OTA distribution

- Switch from Debug build to Release archive with xcodebuild archive
- Use xcodebuild -exportArchive with ad-hoc exportOptions.plist for
  proper Ad Hoc distribution signing (required for Firebase OTA installs)
- Fix CFBundleVersion mismatch in Info.plist (1 → 2) to match project.yml
- Create Config/exportOptions.plist with method=ad-hoc and team 2MJF39L8VY

Previously Debug builds produced a Development provisioning profile that
doesn't include the tester's iPhone UDID, causing 'cannot be installed'.
