refactor: simplify Create Flow dropdown, remove maintenance flow from UI

- Simplify CreateFlowDropdown to 2 clean items: Troubleshooting Flow
  and Procedural Flow (removed 4 AI-assist entries + 1 orphaned duplicate)
- Rename "Troubleshooting Tree" → "Troubleshooting Flow" (per branding)
- Remove Maintenance Flow option from MyTreesPage (hidden for pilot)
- Replace MyTreesPage inline dropdown with shared CreateFlowDropdown
- Remove unused aiEnabled prop, useCachedQuota import, showCreateMenu state
