5a6c80533e Add comprehensive WiFi credentials validation 
Implement WiFi SSID and password validation following IEEE 802.11 standards:

Features:
- SSID validation: length (max 32 bytes), control characters, whitespace warnings
- Password validation for WPA/WPA2/WPA3 (8-63 chars), WEP, and Open networks
- Weak password detection with warnings
- Non-ASCII character warnings
- Input sanitization (trim SSID, preserve password spaces)
- User-friendly error messages

Integration:
- Added validation to wifi-setup.tsx (ESP provisioning flow)
- Added validation to setup-wifi.tsx (batch sensor setup flow)
- Pre-provisioning validation with error/warning alerts
- Password requirements hints in UI

Tests:
- Comprehensive test suite with 42 test cases
- 100% coverage of validation logic
- Tests for all auth types (WPA, WEP, Open)
- Edge cases and warning scenarios

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):
- Real-time validation feedback with error messages
- 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.
