fix: ensure consistent "Recently Added" contacts in ProjectRepresentativeDialog

EntityGrid's recentContacts assumes contacts are sorted by date added
(newest first), but ProjectRepresentativeDialog was receiving contacts
sorted alphabetically from NewEditProjectView, causing it to show
different "Recently Added" contacts than GiftedDialog.

- Changed NewEditProjectView to use $contactsByDateAdded() instead of
  $getAllContacts()
- Added documentation comments to EntityGrid.vue to prevent this issue
  in future reuses
