88bb6d7f8f Configure Root Layout with enhanced redirect logic
Implement comprehensive redirect logic in the Root Layout that:
- Redirects unauthenticated users to login screen
- Checks if authenticated users need to complete onboarding (firstName)
- Prevents redirect loops by only redirecting on initial mount
- Protects tabs from unauthorized access (redirects to login on logout)
- Lets auth screens handle their own navigation via NavigationController

Add comprehensive test suite with 8 tests covering:
- Initial redirect scenarios (authenticated/unauthenticated)
- Onboarding flow (missing firstName)
- Logout protection
- Loading states

Update jest.config.js to support expo-status-bar, expo-splash-screen,
react-native-reanimated, and react-native-worklets transforms.

69c999729f Fix BLE connections not disconnecting on logout
Implemented proper BLE cleanup mechanism on user logout:

**Root Cause:**
- BLE cleanup callback was being set but reference could become stale
- No explicit cleanup call in profile logout handler
- Callback stability issues due to re-renders

**Changes:**
1. app/_layout.tsx:
   - Use useRef pattern to maintain stable callback reference
   - Set callback once with ref that always points to current cleanupBLE
   - Cleanup callback on unmount to prevent memory leaks

2. app/(tabs)/profile/index.tsx:
   - Add explicit cleanupBLE() call in logout handler
   - Import useBLE hook to access cleanup function
   - Ensure cleanup happens before logout completes

3. services/api.ts:
   - Update setOnLogoutBLECleanupCallback signature to accept null
   - Allows proper cleanup of callback on unmount

4. jest.setup.js:
   - Add AsyncStorage mock to prevent test failures

5. Tests:
   - Add comprehensive BLE cleanup tests
   - Test callback pattern and stability
   - Test logout flow with BLE cleanup
   - Test error handling during cleanup

**Result:**
BLE connections now properly disconnect when user logs out,
preventing stale connections and potential resource leaks.

8456e85cfe Remove incorrect beneficiary schema from auth endpoints
Fixed GET /auth/me and POST /auth/verify-otp endpoints to use the correct
beneficiaries table schema. Previously, these endpoints were querying for
fields like email, first_name, last_name, address_street which don't exist
in the actual beneficiaries table, causing empty/incorrect data to be returned.

Changes:
- Updated Supabase queries to fetch correct fields: name, phone, address,
  avatar_url, equipment_status, created_at
- Fixed response mapping to use 'name' instead of 'first_name'/'last_name'
- Added proper equipmentStatus and hasDevices calculations
- Removed spread operator that was adding incorrect fields to response

Added comprehensive tests to verify correct schema usage and ensure
beneficiary data is returned with the proper structure.

7feca4d54b Add debouncing for refresh buttons to prevent duplicate API calls
Implemented a reusable useDebounce hook to prevent rapid-fire clicks
on refresh buttons throughout the application.

Changes:
- Created hooks/useDebounce.ts with configurable delay and leading/trailing edge options
- Added comprehensive unit tests in hooks/__tests__/useDebounce.test.ts
- Applied debouncing to dashboard WebView refresh button (app/(tabs)/dashboard.tsx)
- Applied debouncing to beneficiary detail pull-to-refresh (app/(tabs)/beneficiaries/[id]/index.tsx)
- Applied debouncing to equipment screen refresh (app/(tabs)/beneficiaries/[id]/equipment.tsx)
- Applied debouncing to all error retry buttons (components/ui/ErrorMessage.tsx)
- Fixed jest.setup.js to properly mock React Native modules
- Added implementation documentation in docs/DEBOUNCE_IMPLEMENTATION.md

Technical details:
- Default 1-second debounce delay
- Leading edge execution (immediate first call, then debounce)
- Type-safe with TypeScript generics
- Automatic cleanup on component unmount

521ff52344 Add comprehensive testing and documentation for role-based UI permissions
This commit implements role-based permission testing and documentation for
the beneficiary management system.

The role-based UI was already correctly implemented in BeneficiaryMenu.tsx
(lines 21-25). This commit adds:

- Comprehensive test suite for BeneficiaryMenu role permissions
- Test suite for role-based edit modal functionality
- Detailed documentation in docs/ROLE_BASED_PERMISSIONS.md
- Jest configuration for future testing
- testID added to menu button for testing accessibility

Role Permission Summary:
- Custodian: Full access (all features including remove)
- Guardian: Most features (cannot remove beneficiary)
- Caretaker: Limited access (dashboard, edit nickname, sensors only)

Edit Functionality:
- Custodians can edit full profile (name, address, avatar)
- Guardians/Caretakers can only edit personal nickname (customName)
- Backend validates all permissions server-side for security

Tests verify:
 Menu items filtered correctly by role
 Custodian has full edit capabilities
 Guardian/Caretaker limited to nickname editing only
 Default role is caretaker (security-first approach)
 Navigation routes work correctly

54336986ad Improve serial number validation with comprehensive testing
Added robust serial validation with support for multiple formats:
- Production format: WELLNUO-XXXX-XXXX (strict validation)
- Demo serials: DEMO-00000 and DEMO-1234-5678
- Legacy format: 8+ alphanumeric characters with hyphens

Frontend improvements (activate.tsx):

- Visual error indicators (red border, error icon)
- Proper normalization (uppercase, trimmed)
- Better user experience with clear error messages

Backend improvements (beneficiaries.js):
- Enhanced serial validation on activation endpoint
- Stores normalized serial in device_id field
- Better logging for debugging
- Consistent error responses with validation details

Testing:
- 52 frontend tests covering all validation scenarios
- 40 backend tests ensuring consistency
- Edge case handling (long serials, special chars, etc.)

Code quality:
- ESLint configuration for test files
- All tests passing
- Zero linting errors

74a4c9e8f4 Fix avatar caching after upload with cache-busting
Implemented cache-busting mechanism to prevent stale avatar images
after upload. React Native Image component caches images by URI,
causing old avatars to persist even after successful upload.

Changes:
- Added bustImageCache() utility function in utils/imageUtils.ts
- Appends timestamp query parameter (?t=timestamp) to avatar URLs
- Skips cache-busting for local file://, data: URIs and placeholders
- Applied bustImageCache() to all avatar Image components:
  - Beneficiary detail screen (header, edit modal, lightbox)
  - Beneficiary list cards on dashboard
- Ensured loadBeneficiary() is called after avatar upload completes
- Added comprehensive unit tests for cache-busting logic

Backend already generates unique URLs with timestamps when uploading
to MinIO, but this ensures frontend always requests fresh images.
