feat(export): Stockkarte - a colony's complete record as PDF

New report colony-record-card (button "Stockkarte (PDF)" on the colony
page): master data, current queen and queen history, every inspection as
a table row (strength, eggs, open/capped brood, queen seen, queen cells,
gentleness, swarm drive, feed, measures, notes), treatments with batch
number and withdrawal period, feedings, varroa counts and harvests.
Landscape A4, table header repeated on each page. Whole history by
default, one calendar year with ?year=.
