fix(ui): fix case creation not updating dropdown immediately

- Add cache-busting to /api/cases fetch to prevent stale data
- Use created case path from API response (was using old empty caseData)
- Add selectCaseName parameter to loadQuickStartCases for post-create selection
- Add toast() alias for showToast() to fix "toast is not a function" error
- Prevent duplicate event listeners on case dropdown
- Show "(will be created)" hint when no cases exist
- Add Ralph Wiggum config tab to session options modal
- Add inner-config API endpoint for Ralph loop settings
