feat: add person name and insert time to announcement DTO

- Added PersonName property to AnnouncementDto to display person's full name
- Added lookup logic to fetch person names from Persons table based on phone numbers
- Added InsertTime shadow property retrieval from EF Core to display creation date
- Updated model snapshot with new shadow properties (InsertTime, IsRemoved, RemoveTime, UpdateTime) for Chat entity
