App ID + launcher icon rename: halobestie.* → mybestie

- Customer: com.halobestie.client.client_app → com.mybestie
- Mitra:    com.halobestie.mitra.mitra_app  → com.mybestie.mitra
- iOS bundle IDs renamed to match (no .clientApp/.mitra camelCase legacy)

Mechanical rename touches Android build.gradle/Manifest/MainActivity
package, iOS pbxproj/Info.plist bundle IDs, Firebase configs
(google-services.json + GoogleService-Info.plist + firebase_options.dart),
new HaloBestie/Mitra launcher icons via flutter_launcher_icons (pubspec
config + adaptive-icon resources + AppIcon imageset), and the appId
references in every customer maestro flow + both .maestro/config.yaml
files. brandLogoBg (#FF699F) added to halo_tokens for the launcher pink.

Followup: re-register apps in Firebase consoles using the new package IDs;
strategy memo at project-firebase-env-strategy.
