Closes#29
Backend:
- Add PersonRepository.findCorrespondents / findCorrespondentsWithFilter
(native SQL, orders by shared document count DESC, limit 10)
- Add PersonService.findCorrespondents(personId, q) delegating to the
correct repository method based on whether a query string is present
- Expose GET /api/persons/{id}/correspondents?q= in PersonController
Frontend:
- Add optional restrictToCorrespondentsOf prop to PersonTypeahead
- On focus with the prop set, fetch correspondents immediately (no typing
required) — opens the dropdown showing top correspondents
- On input with the prop set, hit the correspondents endpoint with q= param
- Without the prop, keep existing /api/persons?q= behaviour unchanged
- Wire the prop bidirectionally in /conversations: sender restricts receiver
and vice versa
