Move /mints to API server (port 2121), fix services persistence

- /mints handler moved from captive portal (port 80) to API server (port 2121)
  where it belongs (JSON endpoint, matches portal JS fetch URL)
- Remove stop_services() from STA disconnect and IP loss handlers
- Services now persist across WiFi STA reconnections
- Reduce MAX_STA_RETRY from 5 to 3
