fix(trash): warn about unsaved edits when delete asks nothing

With askBeforeDelete off, clicking ✕ on the entry being edited trashed it
and closed the editor with no prompt whatsoever — a misclick cost the edits
silently. That path now runs the discard gate (no-op unless dirty). When
askBeforeDelete is on, its own confirm still stands alone: one modal.
