test(deck): click the REAL button and read what it prints

Every other packet/card gate drives the RENDERERS. This one drives the UI: it
finds the Card Deck button in the shadow root, clicks it, and captures the
document that reaches the print frame. That is the only path proving the wiring
— records provider, stock picker, language, shared composable, print frame — is
connected end to end. A renderer can be perfect while the button calling it
passes the wrong stock, or nothing at all.

⚠ It intercepts the printed HTML rather than reading the iframe back.
openPrintFrame calls window.print(), which BLOCKS in headless Chromium, and the
frame self-removes on afterprint — reading it back measures a frame that has
already gone and reports 0 cards for a correct deck.

Measured through the real UI: 116 cards at 2.5in 3.5in with 116 QR codes, and
3.5in 2.5in when the stock picker is switched to landscape. Confirmed to fail on
a wrong expected page size.

Also updates the share policy: country-posters moves from 'own-button' to
'header'. Its two-tab MFE now owns sharing, exactly as my-upg-100-list's does —
the gate caught the bundle briefly carrying two affordances after the MFE
landed, which is the regression it was written for.
