Refactor: simplify GiftedDialog with explicit entity type props

Replace complex updateEntityTypes() method with explicit giverEntityType and
recipientEntityType props. This makes the component more declarative and
maintainable by removing hidden logic and making entity type relationships
clear at the call site.

- Remove updateEntityTypes() method and related watchers
- Add explicit giverEntityType and recipientEntityType props with defaults
- Update all views to use inline logic for entity type determination
- Fix entity type preservation in navigation flows
- Enhance query parameter passing for better context preservation
- Fix recipient reset issue in ContactGiftingView
- Resolve entity type mismatch in HomeView project button flow

Files changed:
- GiftedDialog.vue: Remove complex logic, add explicit props
- EntitySelectionStep.vue: Enhanced query parameter handling
- ContactGiftingView.vue: Improved context preservation
- HomeView.vue, ProjectViewView.vue, ClaimView.vue, ContactsView.vue:
  Updated to use explicit entity type props
- Add refactoring documentation
