T0492 sponsorship qr code

[Danielgergely]

• Port the v14 childpack QR concept (child_switzerland) into the shared child_compassion core so the Nordic v18 instance gets it.
• Adds a computed qr_code_data on compassion.child linking to /my2/new-sponsorship/ and renders it on the small (A4) childpack.
• Optional qr code on full and small child packs

T-Rex Logs

What T-Rex did

• I compared the baseline state in the before log to confirm there was no QR compute, wizard option, conditional report image, or full/small optional behavior.
• I compared the after state in the after log and confirmed valid decoded PNG signatures, the sponsorship path /my2/new-sponsorship/321, correct default and overridden UTMs, and QR node counts of 1 and 0 for the two report types.
• I noted that runtime availability and the reusable fallback harness are preserved separately, and that the evidence relies on partial source-backed execution rather than a fabricated QWeb/PDF capture.
• I prepared and linked artifacts to support review, aligning each artifact with the corresponding proof.

@greptile review
pypng is resolved on the first line — importlib.metadata.version("pypng") returns
0.20220715.0 — and passes with no ImportError. Verified: -u child_compassion installs cleanly with pypng declared.
