test(dashboard): drop redundant field-presence tests in SettingsModal

Each of these tests asserts only that a labeled form field exists in
a section. The consolidated "all settings fields are present across
all sections" test (line 497) covers the same space, and the
accompanying payload-roundtrip tests implicitly require the field to
be present before toggling it.

Dropped 7 presence-only tests:
- Recycle worktrees, Show quick chat button, Auto-completion mode
- Include task ID, Auto-resolve conflicts, Add author attribution
- Smart conflict resolution, groupOverlappingFiles type=checkbox

4,317 → 4,206 LOC (-111). 197 tests still passing.
