feat(host): migrate non-economy UTAS routes to Rust + launcher redesign

Host/adapter (deployed to prod-host):
- POST /ut/auth (+/ut/delete/auth): Rust mints sid, opens Rust session, adopts
  persona from body; POST /openfut/account/sync full Rust envelope.
- GET /userMassInfo: full Rust (was proxy+overlay), shared build_user_mass_info.
- GET/PUT /clientdata/<key>: new clientdata_store.rs (JSON-persisted).
- GET /club/stats/{country,league,team}: context-aware club_stats_body
  (nation/league/team buckets).
- GET /store,/match/keepalive,/captcha,/tfa,/livemessage,/activeMessage: StaticAck.
- GET /watchList, /squad/0, /user: Rust handlers.
- host_test.rs updated for the new routing.

Launcher: bump gitlink to c277213 (shareholder-grade redesign + live account panel).
