Add unit tests for various components and stores in the terminal dashboard

- Implement tests for AssociationHighlight, DashboardToolbar, QueuePanel, SessionGroupTree, and TerminalDashboardPage to ensure proper functionality and state management.
- Create tests for cliSessionStore, issueQueueIntegrationStore, queueExecutionStore, queueSchedulerStore, sessionManagerStore, and terminalGridStore to validate state resets and workspace scoping.
- Mock necessary dependencies and state management hooks to isolate tests and ensure accurate behavior.
