Add Wi-Fi scan details display and MQTT publish

- HTML: Add Wi-Fi scan results container to network.html
- Rust: Implement `wifi_scan_details()` with RSSI, channel, auth method
- API & UI: Fetch and display scan results in table format
- MQTT: Publish top 10 networks sorted by RSSI to `/wifi_scan`
