refactor(guides): replace NewGuide with unified GuideForm

- Merge useNewGuide and NewGuide into useGuideForm and GuideForm
  to handle both create and edit flows
- Add /edit-guide/:id route pointing to GuideForm
- Replace Edit button in Guide view with Link to edit route
- Add defaultValue to Frame title input for edit pre-population
- Delete NewGuide.tsx, NewGuide.css, useNewGuide.ts
