Merge branch 'main' into feat/vaccinations-phase-1

The visit stage's second half landed while this was in flight and both
touched the same three places. Resolved as one set: the link facade
carries the reverse document-to-visit direction and the new dose pair
side by side, the sharing literals hold both sets of admissions with the
count re-added on top, and the language bundles take the shorter module
description the trunk settled on.
