Add JWT_SECRET environment variable to ingress deployment

Added JWT_SECRET configuration to the ingress service deployment template and values.yaml. This provides the JWT secret key needed for token generation and validation in the insights-ros-ingress service.

Changes:
- Added JWT_SECRET environment variable to deployment-ingress.yaml template
- Added jwtSecret configuration field to values.yaml with default dev value
- Ensures ingress service has proper JWT configuration for authentication
