feat: Wi-Fi station connectivity - #11

Conversation
Require the esp_wifi/esp_event/esp_netif/esp_timer components and enable software BLE/Wi-Fi coexistence. Add a custom partition table with a larger app partition, since the BLE + Wi-Fi binary exceeds the default 1 MB; nvs is kept at 0x9000/0x6000 to preserve the host provisioner contract.
Add connectivity/wifi following the hexagonal structure: the IWifiStation port, WifiService (reads credentials from IWifiConfig), the esp_wifi adapter and the Wifi facade. Connects asynchronously in station mode using the stored credentials, reports connection status and reconnects indefinitely on drop. Caps TX power after start to work around the ESP32-C3 SuperMini antenna. Wire it in main to start after provisioning.
Add Doxygen comments to the override methods of the flash-backed config adapters and the NimBLE GATT server, matching the documentation style used elsewhere.

Summary
Adds
connectivity/wifi: a Wi-Fi station that uses the credentials provisioned over BLE (IWifiConfig) to connect to the network, so the device actually goes online. Same hexagonal structure asconnectivity/provisioning.IWifiStation(domain) +Status { Disconnected, Connecting, Connected }.WifiService(application) — reads SSID/password fromIWifiConfig; if there are no credentials it logs and returns without crashing.EspWifiStation(infrastructure) —esp_wifistation adapter. Event-driven (WIFI_EVENT/IP_EVENT), non-blocking, reconnects indefinitely on drop via a one-shotesp_timer. Caps TX power after start to work around the ESP32-C3 SuperMini antenna.Wifi(facade) —start()/stop()/isConnected()/onStatusChange(); wired inmainto start after provisioning.Design decisions: asynchronous + status query, BLE/Wi-Fi software coexistence (BLE keeps advertising), indefinite reconnection.
Build
esp_wifi esp_event esp_netif esp_timer; software coexistence enabled.partitions.csv(3 MB factory) is added, keepingnvsat0x9000/0x6000(provisioner contract). Flash usage ~33% of the new partition.Also included
Notes
start(); applying credentials freshly provisioned over BLE currently requires a reboot (the future orchestrator/FSM will coordinate live re-connection).config::wifi::MAX_TX_POWER(34 = 8.5 dBm) for boards with different RF.Verification
make -C firmwarebuilds cleanly (Flash ~33%, RAM ~11%).connectivity/wifilogs reachConnectedwith an IP; drop the AP and confirm it retries and reconnects; confirm BLE still advertises (coexistence).
