Print page: tab reorder (PDF default, drop embedded preview) + settings carry-over from /display

[WilfordGrimley]

The two remaining D10 pieces after #306 landed the funnel linkage:

1. Tab reorder + preview removal (owner decision, 2026-07-21): the Print page's tabs become PDF · MakePlayingCards · NotMPC · PringlePrints with PDF as default/first, and the PDF tab drops its embedded preview (/display's center sheet is the preview; the tab keeps generation/settings). Implemented via a showPreview={false}-style additive prop per the design spec's D10 row.

2. Settings carry-over (Add /display Finish footer with co-equal Save Deck/Print + save-before-PDF draft backup (#275) #306's documented gap): /display's Page Setup values (paper size, bleed, margin profile, card spacing, guides) don't currently reach the classic PDFGenerator's own separate settings when arriving via the finish funnel — a user who configured their sheet on /display should not re-enter values on the Print page. Wire the funnel navigation to carry the display settings into the PDF tab's state (one-way on arrival; the classic tab stays independently usable). Composes with Converge /display's Card Spacing control onto upstream's existing spacing inputs (extract shared component) #298's spacing-inputs extraction.

Sequencing: next in the display queue after in-flight work (#305 overhaul, #298 convergence).
