feat: Enhance Cloud Run deploy command with advanced configuration op…

…tions

- Add comprehensive environment variable management (set, update, remove, clear)
- Add secret management for both environment variables and volume mounts
- Improve CLI documentation with detailed long description and examples
- Refactor deploy command to support more flexible service configuration
- Add flag validations to prevent conflicting environment variable and secret configurations
