- Replaced all instances of "Unnamed Member" with "Someone Unnamed"
- Removed unused UNNAMED_MEMBER constant
- Renamed UNNAMED_PERSON to THAT_UNNAMED_PERSON to match its value
- Renamed UNNAMED_USER to UNNAMED_PERSON and changed the value to "unnamed person"
Replace string-based entity type matching with DID-based logic for "You" and "Unnamed" entities. Treat these as regular person entities instead of special types.
- Remove "special" type from EntitySelectionEvent interface
- Update EntityGrid to emit "You" and "Unnamed" as person entities
- Simplify SpecialEntityCard emit structure (remove entityType parameter)
- Refactor GiftedDialog to process all person entities with DID-based logic
- Update ContactGiftingView and HomeView to use DID-based entity creation
- Remove string literals "You" and "Unnamed" from method signatures
- Split openDialog into separate methods to improve code readability and maintainability through method extraction
- Add receiver name fallback in GiftedDialog when receiver exists but has no name
- Enhance shouldShowYouEntity to prevent selecting "You" as both giver and recipient
- Improve labeling of "(No name)" entities while retaining original entity object properties
- Apply special styling to "Unnamed" and "(No Name)" entities
- "You" is displayed conditionally, similar to GiftedDialog behavior
- "Show All" is hidden in GiftedDialog when accessed from ContactGiftingView (redundant)
