fix: EVENT msg buffer underflow + WS write loop + WPA3 auth

- Fix buffer size for ["EVENT",...] wrapper: was 8+event_len+1,
  needed 10+event_len+2 (9 char prefix + ] + null). snprintf was
  truncating the closing bracket, causing relay JSON parse errors.
- Add write loop in ws_send_text for large payloads that don't fit
  in a single esp_tls_conn_write call.
- Change STA auth threshold from WPA2_PSK to WPA3_PSK for
  compatibility with WPA3 access points.
- Announcements now successfully stored on relay.primal.net!
