feat(vaccinations): link documents to doses, with the upload suggestion

- from the record: a document link picker on the capture form, gated on the
  documents module (blanked when off, never post-filtered)
- from the upload: a VACCINATION scan offers to file against a dose recorded
  within the shared ±7-day window; a single candidate pre-selects, two offer a
  picker with nothing pre-selected (WR-8 seen red on the pre-select rule,
  reverted by content hash), zero shows nothing, and it never blocks the upload
- the suggestion rule reuses the visit moment's window constant rather than
  forking it; it registers with the shared filing module when that lands
- suggestion and link copy in six locales
