feat: increase resource limits and improve readiness checks

Increases memory requests and limits in the Kubernetes deployment 
configuration to ensure better performance under load. Enhances 
the readiness and liveness probes by correcting the path and 
adding a liveness probe to improve service reliability. Updates 
Code by cleaning up session data after a successful token exchange 
and formats OpenID configuration response for better readability. 
Adds `.claude/` to .gitignore to prevent unwanted files from 
being tracked.
