Phase 2 Task 35. Adds OAuth Google/Microsoft sign-in to the register flow, gated on the public SELF_SERVE_ENABLED flag, and hides the legacy invite-code field when self-serve is on. - New `useAppConfig` hook + `configApi`. One-shot module-cached fetch of `GET /api/v1/config/public`; falls back to `VITE_SELF_SERVE_ENABLED` env var (default false) if the endpoint is unreachable. - New `OAuthCallbackPage` mounted at `/auth/google/callback` and `/auth/microsoft/callback` (public, NOT inside ProtectedRoute). Posts the authorization code to the backend, persists tokens, hydrates the auth store via fetchUser, and redirects to `/welcome` (new) or `/` (returning). - `RegisterPage` now renders OAuth buttons + email/password divider when `self_serve_enabled` is true and only emits buttons for providers the backend reports as configured. Invite-code field hidden in that mode. Captures `?plan=pro` into `localStorage.rf-intended-plan` on mount. - `authApi` gains `googleCallback(code)` / `microsoftCallback(code)`. - `frontend/.env.example` + `frontend/Dockerfile` document and bake the three new VITE_* build-time variables (Lesson 60: Vite needs ARG+ENV). - Vitest coverage for the three required cases plus the plan-param capture.
