Rebrand from Casera/MyCrib to honeyDue

Total rebrand across KMM project:
- Kotlin package: com.example.casera -> com.tt.honeyDue (dirs + declarations)
- Gradle: rootProject.name, namespace, applicationId
- Android: manifest, strings.xml (all languages), widget resources
- iOS: pbxproj bundle IDs, Info.plist, entitlements, xcconfig
- iOS directories: Casera/ -> HoneyDue/, CaseraTests/ -> HoneyDueTests/, etc.
- Swift source: all class/struct/enum renames
- Deep links: casera:// -> honeydue://, .casera -> .honeydue
- App icons replaced with honeyDue honeycomb icon
- Domains: casera.treytartt.com -> honeyDue.treytartt.com
- Bundle IDs: com.tt.casera -> com.tt.honeyDue
- Database table names preserved
