Add comprehensive tests for WiFi Setup screen (auth flow)

Add 35 tests covering the complete WiFi Setup wizard flow:
- Device scanning and discovery
- BLE device connection
- WiFi network scanning and selection
- Password entry with visibility toggle
- WiFi provisioning via ESP32
- Success state and navigation

All tests pass. Existing implementation was verified to be
fully functional; this commit adds missing test coverage.
