Add comprehensive WiFi credential validation
- Add real-time validation for WiFi credentials with password strength indicator - Add validateRealTime() for immediate UI feedback as user types - Add parseWiFiErrorResponse() for user-friendly error messages - Add prepareCredentialsForDevice() for pre-transmission validation - Block BLE protocol delimiter characters (| and ,) in credentials - Create WiFiPasswordInput component with strength bar and validation hints - Update BLEManager with improved error messages and pre-validation - Update MockBLEManager with simulation scenarios for testing - Add 62 comprehensive tests for all validation functions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
