TF-4269 Fix Sentry release version sync across platforms

Use --dart-define=SENTRY_RELEASE=<full-tag> in Fastlane so the app
reports the same version string to Sentry as CI uses when uploading
symbols, bypassing iOS CFBundleShortVersionString stripping.

- Android Fastfile: add --dart-define=SENTRY_RELEASE (build-name unchanged)
- iOS Fastfile: pass DART_DEFINES via xcargs (increment_version_number unchanged)
- Dart: read SENTRY_RELEASE dart-define first, fall back to PackageInfo.version
- NSE/Web unaffected: NSE reads from Keychain, Web falls back to PackageInfo
