fix: Gateway status discrepancy — foreign detection, claim action, banner sync

- Services page: foreign Gateway now shows warning dot (yellow) instead of green
- Add claim_gateway command (Rust + dev-api + frontend API) to adopt foreign Gateway
- Services page: add "Claim Gateway" button for foreign Gateway instances
- Top banner: distinguish foreign Gateway (warning + claim) vs stopped (info + start)
- app-state: expose isGatewayForeign(), pass foreign flag to onGatewayChange listeners
- Services page actions now immediately sync global Gateway state (no 15s poll wait)
- Relax owner matching: cli_path missing on either side no longer triggers foreign
- Add i18n keys: foreignGatewayBanner, claimGateway, claimSuccess, claimFailed, processing
