auth-fixes (#12)

## Summary

Wire spec-driven auth into the frontend. Auth config (server URL, paths) is extracted from the served OpenAPI spec by `AppProvider`. `AuthProvider` receives the config as a prop. 401 responses from both the main API and the auth server dispatch an `auth:unauthorized` event that triggers redirect to `/login`. Fix `ProfileRoutes` URL duplication bug.

## Changes

### Auth config from spec
- **`main.jsx`** — `AppProvider` wraps everything, loads spec, exposes `authConfig`. `AuthProvider` receives `authConfig` from `useAppContext()`. `onUnauthorized` passed to both `AppProvider` and `AuthProvider` wires `navigate("/login")`.

### 401 handling
- **`AppProvider.tsx`** — remove `onUnauthorized` prop (handled by `AuthProvider`'s event listener instead, avoiding double-navigation).
- **`useApi.ts`** — 401 response interceptor dispatches `auth:unauthorized` CustomEvent on `window`.

### Profile routing fix
- **`Admin.tsx:ProfileRoutes`** — replace nested `<Routes>` (which caused `/profile/me/me` URL duplication with React Router v6) with `useLocation()`/`useNavigate()` conditional rendering. Only allows `/profile/me` and `/profile/me/edit`.
- **`Admin.tsx:ProfileComponentWrapper`** — replace `pushState() + reload()` with React Router `navigate()` for both `onEdit` and `handleSubmit`.

### Debug logging
- Temporary console logs at every navigation point for diagnosing remaining issues.
