The plan previously suggested the UI wouldn't change — only the code would be
refactored. Updated to make explicit that:
- Dobradinhas editor changes from RelationChipCell to the same
CampaignCellEditOverlay + Command + chips as Assessores/Liderancas.
- Liderancas display gains an avatar stack matching Assessores/Dobradinhas.
- Inline create is always name-only across all three columns (leadership
phone is added later on the detail page).
- Assessores is the reference — its UI doesn't change.
