feat(FN-1673): add editable AI suggestion drafts before acceptance

- Add editable drafts for AI-generated milestone and feature suggestions before acceptance
- Users can edit suggestion title and description before creating the actual items
- Draft edits persist when accepting individual or all suggestions
- Add empty/whitespace title validation to prevent accepting blank suggestions
- Add comprehensive tests for suggestion generation, editing, and acceptance
- Fix prop type mismatch between RoadmapsView and MilestoneCard components
- Add missing clearMilestoneSuggestions function to useRoadmaps hook
- Update refs to synchronize immediately with state for proper test behavior
- Add generateMilestoneSuggestions to API mock in component tests
- Add documentation for the AI suggestion feature in dashboard-guide.md
