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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
