test: update PdfEditor tests for event-driven placement detection

Replace obsolete polling-based tests with new tests for the event relay pattern:
- Remove: 'schedules a deferred completion check after a placement interaction'
- Remove: 'emits adding-ended when object count increases after adding mode starts'
- Remove: 'emits adding-ended when adding mode finishes without object delta'
- Remove: 'keeps waiting while adding mode is active and count has not changed'
- Remove: 'ignores completion checks when no add session is pending'
- Remove: 'RULE: document listener lifecycle' test suite

Add: 'RULE: pdf-elements event relay' test suite with:
- 'relays pdf-elements:adding-ended event to pdf-editor:adding-ended'
- 'relays cancelled event with reason'

Update type definition PdfEditorVm:
- Remove: checkSignerAdded, scheduleSignerAddedCheck
- Add: handleAddingEnded(event: Event)

All 60 PdfEditor tests now pass with event-driven model.
