Documents that the token endpoint accepts both JSON and form-urlencoded
bodies per OAuth2 spec, with form data parsed by body-parser middleware.

The OIDC request handler was not properly forwarding sign-in requests.
Added a dedicated handler that:
- Directly calls Better Auth's handler
- Properly handles Set-Cookie headers for session cookies
- Exposed getHandler() method from BetterAuthService
- Added trustedOrigins configuration to allow cross-origin requests

The OIDC login page was using our custom /api/v1/auth/login endpoint
which returns tokens but doesn't set session cookies. Better Auth's
OIDC provider needs session cookies to recognize logged-in users.
Changes:
- Update login page to use /api/auth/sign-in/email (Better Auth native)
- Add sign-in endpoint handler in oidc.controller.ts
- Add route exclusion in main.ts for the sign-in path
This fixes the infinite redirect loop where users would log in but
then be sent back to login because the OAuth2 authorize endpoint
couldn't detect the session.

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.
