Add R./V./repeat labels to per-book responsory pool output

getResponsoryForBook's joinResponsory concatenated the r/v text with a
bare newline and no "R."/"V." labels at all, unlike every other
responsory source in the app (octave-readings' own responsory field,
nocturn-readings' inline responsory, and the new per-Common-category
pool) which all include the full "R. ...\n* ...\nV. ...\nR. ..."
convention. User caught this looking at the rendered Judith entry.

Fixed by computing the repeat line from the existing "*" marker
already present in the pool's r text. npm test (2025 passed) and
tsc --noEmit pass.
