feat: Role based Cadence-web.

- UI RBAC aligned with Cadence JWT auth: tokens come from cookie (cadence-authorization) or env (CADENCE_WEB_JWT_TOKEN), are forwarded on all gRPC calls, and claims/groups drive what the UI shows/enables.
- Auth endpoints: POST /api/auth/token to set the HttpOnly cookie, DELETE /api/auth/token to clear it, GET /api/auth/me to expose public auth context.
- User context middleware populates gRPC metadata and user info for all route handlers.
- Domain visibility: getAllDomains filters by READ_GROUPS/WRITE_GROUPS. Redirects respect the filtered list.
- Workflow/domain actions: start/signal/terminate/etc. are disabled with “Not authorized” when the token lacks write access;
- Login/logout UI: navbar shows JWT paste modal when unauthenticated.
