Subject: feat(auth): store JWT in HTTP-only cookie instead of JS-accessible
 cookie

Prevent XSS-based token theft by making the JWT inaccessible to
JavaScript. The backend now sets/clears the cookie via Set-Cookie
headers, and the frontend retrieves user info from /api/me instead
of decoding the JWT directly.

- Add JWTCookieMiddleware to parse cookie and inject claims into context
- Add /me and /logout endpoints to OpenAPI spec and handlers
- Update PostLogin to return user object + Set-Cookie header
- Replace Authorization header auth with cookie-based auth throughout
- Rewrite frontend auth to use /api/me instead of jwt-decode
- Remove jwt-decode dependency
- Configure CORS with credentials for local dev
