fix(provisioning): fast-fail wifi on bad PSK / missing SSID

Match the failure path's latency to the happy path. Before: a wrong
password meant the user stared at the yellow Step 1/2 screen for the
full 30 s WIFI_TIMEOUT_MS before the red retry repaint started — total
~50 s to "Connection Failed" visible. After: WL_CONNECT_FAILED and
WL_NO_SSID_AVAIL bail attempt_wifi() immediately, so the red repaint
starts within a few seconds of the radio giving up — total ~25 s,
matching the happy-path-to-Step-2/2 timing.

Also collapse the duplicate boot-time poll loop in main.cpp onto the
shared attempt_wifi() so the same fast-fail covers boot-with-stored-
creds, not just captive-portal submission.

Tests: FW-15a (auth fail) and FW-15b (no SSID) assert millis() never
reaches WIFI_TIMEOUT_MS on those statuses. Existing FW-15 tightened
to use WL_DISCONNECTED so it actually exercises the timeout path.
