fix: update Playwright test selectors to match actual UI

- Use specific command palette placeholder to avoid ambiguous matches
- Fix 'Quick Actions' scoping (two elements with same text)
- Fix 'Resolved' exact match on session detail page
- Fix tree editor to use getByText instead of getByDisplayValue
- Fix 'Add Step' strict mode by using .first()
- Fix fallback description placeholder text
- Update playwright.config.ts to use port 5433 and resolutionflow DB
- Update FlowPilot chat selectors to match actual page layout

11/17 new tests now passing. Remaining 6 need procedural session
navigation investigation.
