feat: sheet templates, margin profiles and delivering the sheet

Seeds the four sheet setups Till actually prints (Kita set, small school set,
full passport sheet, two 10x7,5 on 10x15 paper). A multi-format template
applied to a single image clones it into every format, so one click yields the
whole set. Margin gets one-click borderless / 5 mm / 10 mm profiles, and the
finished PDF can be pushed to Picdrop, the NAS or any extra target.
