feat(summons): add edit mode to summon detail page

- Add edit mode state management (editMode, editData, isSaving)
- Use DetailScaffold wrapper for consistent edit UI
- Import and integrate section components:
  - SummonMetadataSection, SummonUncapSection
  - SummonTaxonomySection, SummonStatsSection
- Add Nicknames, Dates, Links sections in edit mode
- Connect saveChanges to entityAdapter.updateSummon()
- Invalidate TanStack Query cache after successful save
