fix(k8s): optimize API and frontend resource configuration

API deployment:
- Add .NET GC optimization flags (gcServer=0, GCConserveMemory=9)
- Increase memory requests/limits for stability
- Add GCHeapCount and gcConcurrent settings

Frontend deployment:
- Adjust resource limits for better stability
- Update probe configurations
