fix stale test assertions after note-page interaction changes — TDD

- NoteEquipTitleViewTest.test_doff_returns_200: assert greeting + title fields now returned by doff_title view
- NoteEquipTitleTest FT: click note item to lock before reading DON/DOFF text — opacity:0 by default makes .text return empty
