httpd_txrx warned on every client reset (errno 104) and httpd_uri on
every 404 (the UI polls /api/player every 2 s until step 7), flooding
syslog. Both set to error level; our handlers log the 4xx that matter.
Remaining known line: 'httpd_resp_send_err: error calling setsockopt :
22' (error level) when a client closes right after a 4xx; a harmless
race in IDF's CONFIG_HTTPD_ERR_RESP_NO_DELAY handling, the response is
already delivered.
Verified via syslog: 10 status + 10 /api/player requests, no httpd lines.
