Once StaClient::connect() had already succeeded once, a later link
loss (router rebooted, password changed, device moved) just retried
esp_wifi_connect() forever with no bound and no fallback -- the only
recovery path was a power cycle, since BLE provisioning only ever
started from startSetupMode() (no stored credentials, or the initial
boot-time connect attempt exhausting its own bounded retry count).
connect() now optionally takes the secure store and device identity;
when set, a link lost for longer than ~1 minute starts BLE
provisioning (net::ble_provisioning::start(), same GATT flow as first-
time setup) alongside the still-ongoing STA reconnect attempts -- it
doesn't stop trying Wi-Fi on its own, it just also gives the app a way
in over Bluetooth if Wi-Fi doesn't come back.
