fix: include Wirkstoff, Charge, and Wartezeit in the annual treatment report

The colony annual PDF report's treatment section only ever printed
date/product/amount - activeIngredient, batchNumber, and
withdrawalPeriodDays (added earlier this session specifically for
Wartezeit compliance) existed on the Treatment record but never made
it into the one document a beekeeper would actually hand to a
Veterinäramt inspector or keep as their Bestandsbuch-style compliance
record. Silently missing the withdrawal period from the printed
record undermines the whole point of tracking it.

Also adds the first tests for annual-reports.ts (previously untested).
