feat(weapons): add edit mode to weapon detail page

- Add edit mode state management (editMode, editData, isSaving)
- Use DetailScaffold wrapper for consistent edit UI
- Import and integrate section components:
  - WeaponMetadataSection, WeaponUncapSection
  - WeaponTaxonomySection, WeaponStatsSection
- Add Nicknames, Dates, Links, Character (recruits) sections in edit mode
- Connect saveChanges to entityAdapter.updateWeapon()
- Invalidate TanStack Query cache after successful save
