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.

+| Column | Type | Required | Description | Example |
+|--------|------|----------|-------------|---------|
+| `id` | string | Yes | Unique task identifier | `"SCAN-001"` |
+| `title` | string | Yes | Short task title | `"Scan Button component"` |
+| `description` | string | Yes | Detailed task description (self-contained) | `"Scan Button component for UX issues..."` |
+| `deps` | string | No | Semicolon-separated dependency task IDs | `"EXPLORE-001"` |
+| `context_from` | string | No | Semicolon-separated task IDs for context | `"EXPLORE-001"` |
+| `exec_mode` | enum | Yes | Execution mechanism: `csv-wave` or `interactive` | `"csv-wave"` |
+| `role` | enum | Yes | Role name: `explorer`, `scanner`, `diagnoser`, `designer`, `implementer`, `tester` | `"scanner"` |
+| `component` | string | No | Component name being processed | `"Button"` |
+
+#### Computed Columns (Set by Wave Engine)
+
+| Column | Type | Description | Example |
+|--------|------|-------------|---------|
+| `wave` | integer | Wave number (1-based, from topological sort) | `2` |
+| `prev_context` | string | Aggregated findings from context_from tasks (per-wave CSV only) | `"[EXPLORE-001] Found 15 components..."` |
+
+#### Output Columns (Set by Agent)
+
+| Column | Type | Description | Example |
+|--------|------|-------------|---------|
+| `status` | enum | `pending` → `completed` / `failed` / `skipped` | `"completed"` |
