Fix hermes_privat_v112 crop to match the v1.1.2 layout

[MaxWinterstein]

hermes-privat-v112 was created in 85dec85 by renaming hermesPrivatV111; no coordinate was changed. Measured against a real v1.1.2 label, several source rectangles miss content:

element	rectangle in code	actual ink	missing
Titel	y 180–224	y 165–205	15 px at the top
Empfänger Land	y 1212–1242	y 1217–1244	2 px at the bottom
Zahlungscode	x 250–1005	x 260–1010	5 px at the right ("bezahlt")
Sendungsnummer	x 306–606	x 260–602	46 px of bar length

The title was also drawn at dst y = 0 and the divider ran from y 0 to y 696, flush with the canvas edge instead of inside the 12 px (1 mm) zone crop.js marks in debug mode.

Resulting ink in the 1642×696 output canvas:

	before	after
Titel	y 0..25 (26 px of 41 px visible)	y 15..55
Zahlungscode	x ..1639	x ..1637, "bezahlt" complete
Sendungsnummer	y 380..675 (296 px)	y 338..679 (342 px)
all elements	y 0..695	y 12..683

Also included: the first sample for this label version (samples/hermes/hermes_privat.png / .pdf, generated with the app itself) and the two README links enabled. The previous sample image still showed the old v1.0.2 "Privatservice" layout, which is probably why it was commented out.

Gewichtswarnung and Zusatz EU are left untouched — my label does not contain them, so I could not measure them.

How the numbers were measured: the page was rendered with the app's own pdf.js at scale 4, every drawImage call recorded through a Proxy on the 2D context, and the real ink bounding boxes measured instead of eyeballing coordinates. The label's fonts are embedded, so the values do not depend on the renderer.

The anonymised label I measured against sits on a side branch of my fork, in case you want to re-check: addresses, both shipment IDs, barcode, both QR codes and the tracking link annotation are replaced, and it still reproduces the clipping.
