feat: Add interactive setup controls to dashboard UI

Users can now run prerequisite commands directly from the dashboard:
- Run EDA pipeline button (interactive subprocess execution)
- Generate test cases button with configurable count
- Real-time status refresh button
- Spinner and progress indicators during execution
- Error handling with expandable details
- Success messages with automatic page refresh
- Fallback manual command instructions

Benefits:
- No need to switch to terminal for setup
- Better UX with guided setup workflow
- Clear status indicators show what's ready
- All setup can be done from one place

-    1. **Run EDA pipeline**: `uv run court-scheduler eda`
-    2. **Generate test cases** (optional): `uv run court-scheduler generate`
-    3. **Parameters extracted**: Check that `configs/parameters/` exists
+    **How to set up**:
+    - Use the interactive buttons in the "Setup Required" section above (if shown)
+    - Or run commands manually:
+      - `uv run court-scheduler eda`
+      - `uv run court-scheduler generate` (optional)
