feat: point third-party mode at upstream Yu9191 modules

- subscription URLs now resolve directly to upstream modules (gh-proxy
  mirror / raw), dropping project-owned module and script copies
- remove Resources/ThirdPartyProxyModules and ThirdParty/WlocScripts,
  their pbxproj references, and the contract-test module checks
- third-party save sends lon/lat/acc matching the upstream settings
  script; motion-state simulation is unavailable (upstream lacks it)
- surface the iOS 27 beta 6 gs-loc MITM limitation in the app setup and
  README (zh/en)
