Amazfit GTS 3: Fix battery drain due to unanswered weather requests

- Reply with HTTP 404 to unknown weather endpoints
- Add some missing fields to weather responses

The official Zepp app itself gets a 404 when calling a /weather/tide
endpoint, so we don't know what the watch is supposed to receive.

Weather also seems to still not work correctly on the GTS 3, but this at
least fixes the request spam that was coming from the watch on the tide
endpoint.
