Add input/output sanitization and security improvements

[umago]

• Change operator logger from development to production mode to avoid leaking heavy stack traces that can contain internal information on warning+ log levels. Development logs can still be enabled using the --zap-devel argument [0].

• Add RunAsNonRoot and drop all Linux capabilities on the Postgres container.

• Add kubebuilder validation constraints:

  • URL pattern on LLMEndpoint
  • Format pattern on OGXLogLevel
  • minimum=1 on MaxTokensForResponse

• Add HTTP security headers to the console plugin nginx config (X-Frame-Options, X-Content-Type-Options, Referrer-Policy)

could not run steps: step openstack-lightspeed-kuttl-4-18 failed: failed to wait for the created cluster claim to become ready: timed out waiting for the condition 

This looks painful. We should figure out whether we can do something about it. I'm thinking we might be maybe requesting too much resources (?) idk.

@lpiwowar yeah I think it's broken somehow, super painful. I just ran the kuttl tests again locally and everything is good. Yeah I will take a look at other projects and see if it's failing too, but as u said, maybe it's the amount of resource ? Idk
