Refactor: improve dialog logic and entity handling

- 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
