- Add ConsoleSessionStore for managing console session state including tenants, profile, and token information.
- Create OperatorContextService to manage operator context for orchestrator actions.
- Implement OperatorMetadataInterceptor to enrich HTTP requests with operator context metadata.
- Develop ConsoleProfileComponent to display user profile and session details, including tenant information and access tokens.
- Add corresponding HTML and SCSS for ConsoleProfileComponent to enhance UI presentation.
- Write unit tests for ConsoleProfileComponent to ensure correct rendering and functionality.
