RAK13800 Ethernet improvements

Fixes (#3618) by allowing more time for slower requests.
Resolve Syslog not maintaining client causing issues on RAK13800.
Resolve Ethernet static IP setting subnet as gateway IP.
Reduce comment and log message ambiguity around API.
Remove duplicate #if !MESHTASTIC_EXCLUDE_WEBSERVER block.
