Review and confirm UK Gov Fuel Finder API terms of service for redistribution

[GavT]

Summary

The backend consumes the UK Government Fuel Finder API (fuel-finder.service.gov.uk) via OAuth2 client credentials. Before public launch, confirm that the API terms of service permit:

1. Redistribution of fuel price data to consumers via a mobile app
2. Caching of data (currently cached in-memory on restart)
3. Commercial use (if Fueller becomes a paid or ad-supported product)
4. Attribution requirements — does the app UI need to credit the data source?

Action

• Review API T&Cs at the UK Gov Fuel Finder developer portal
• If redistribution is restricted: explore alternative data sources or apply for a redistribution licence
• Document the agreed terms in LEGAL.md in the repo root
