test(02-01): add feature tests for inline note UI

- Test note count badge renders with correct count from withCount
- Test Alpine.js directives present in HTML (noteFormOpen, submitNote, x-model, :disabled)
- Test 備忘錄 column header renders
- Test zero-note members show 0 count
- Test correct note store route URL embedded for each member

All 5 tests pass. No regressions in 7 Phase 1 tests.
