C3D-0256 · 260714 Huckaby: fix 17X11 viewport scale and bring the high sheet furniture down done

(A) The landscape viewport is half the portrait viewports height, so carrying the same view height gave 1inch=65.30feet. Sets view height to paperHeight*32.49 to restore 1inch=32.49feet. (B) The 105 entities rejected by the last pass all failed on Y, not X - the north arrow, SS_LEGEND and GA W.GRID sit at y 13.5-16.5 on the tall portrait sheet, off the top of an 11-inch landscape sheet. Copies them with dy=-5.6 so they land top-right, clear of the bottom-left title panel.

C# payload

// Two corrections to the 17X11 sheet:
//
// A. SCALE. The landscape viewport is 8.147 tall vs the portrait's 16.373, so carrying the same
//    view height (532.00) halved the scale to 1"=65.30'. For 1"=32.49' the view height must be
//    8.147 * 32.49 = 264.70.
//
// B. THE MISSING FURNITURE. C3D-0254 shifted the notes +6.5 in X only and 105 entities were
//    rejected - ALL of them for Y, not X: they sit at y 13.5..16.5 on the tall portrait sheet,
//    which is off the top of an 11-inch landscape sheet. They are the north arrow (y~13.5-14.4),
//    the legend block (y~13.4-16.6) and the GA W.GRID text. They need to come DOWN as well as
//    across, into the band the portrait sheet used for its viewport.
