Fix WiFi setup flow and improve hotspot management

- Fix deviceID overwrite bug: preserve manual configuration across reboots
- Use deviceName as hotspot SSID for better device identification
- Implement live WiFi scanning instead of reading stale CSV data
- Improve hotspot management with dynamic connection detection
- Add database status updates on WiFi connection success/failure
- Hide password in logs for better security
