fix: gateway authentik port from 80 to 9000

NetworkPolicy allows gateway→iam only on ports 9000/9443, but config
used port 80 for JWKS fetch and token endpoints. This caused
'operation not permitted' errors and JWKS refresh failures.

Affects:
- auth.jwksUrl: uses port 9000 (Authentik HTTP)
- auth.tokenUrl: uses port 9000 for token exchange
- iam adapter upstream: routes to port 9000

Fixes: Gateway unable to validate JWT tokens, all chat/inference requests
returned 401 with 'token is unverifiable' error.
