Kotlin migration (phases 3-5):
- Port all DTOs, helpers, models, workers, receivers, and services from Java to Kotlin
- Room DB files ported to Kotlin with all logic kept commented out (not yet enabled)
- Add SMSFilterScreen and SMSFilterViewModel in Compose (replaces Java SMSFilterActivity in new UI)
- All helpers exposed as Kotlin objects with @JvmStatic for Java interop
Onboarding improvements:
- Rewrote copy on all 5 onboarding screens (Welcome, Credentials, DeviceSetup, Permissions, SetupComplete)
- Added receive SMS toggle on SetupCompleteScreen (defaults on)
- Gateway now set to enabled by default after successful registration
Dashboard improvements:
- Add receive SMS toggle and SIM subscription ID display in device card
- Add permission warning card when SMS permissions are missing
- Remove all-time stats section (replaced by subscription usage bars)
- Trim Quick Actions to Dashboard + Docs; move Get Support and Share to Settings
- Merge user greeting into TopAppBar subtitle
- Device ID now has inline copy button
Dashboard UI polish (community review fixes):
- Redundant Enabled badge removed; only shows when gateway is Disabled
- Add Gateway label below the main switch for clarity
- Replace infinity symbol with Unlimited in usage display
- SIM subscription IDs use neutral color instead of primary/orange
- Status bar matches background color instead of primary orange
