Better Auth's OIDC discovery document advertises endpoints at
/api/auth/oauth2/* paths. Add routes for these native paths to
ensure Matrix Synapse and other OIDC clients can complete the
authorization flow.
Routes added:
- GET /api/auth/oauth2/authorize
- POST /api/auth/oauth2/token
- GET /api/auth/oauth2/userinfo
- GET /api/auth/jwks

Better Auth's discovery document points to /api/auth/jwks,
so we need to expose this route directly in NestJS.
