fix: WiFi auth + AP channel + PMF for upstream connectivity

- Add TK-GAESTE open network as fallback
- Fix EnterSSID-2.4GHz password (c03rad0r123!)
- Set auth threshold to WIFI_AUTH_OPEN for open network support
- Enable PMF capable mode for WPA2 AP compatibility
- Set AP channel to 6 (ESP-IDF auto-adjusts to match STA channel)
- Use WIFI_ALL_CHANNEL_SCAN for STA scan method
