C3D-0247 · 260714 Huckaby: create the 17X11 landscape layout done

Creates layout 17X11, sets ANSI full-bleed B media with 90-degree plot rotation for landscape and monochrome.ctb, then inserts SS_BLOCK_17X11 at the sheet right edge (17.29, 0.29) with all attribute references attached so the title block is fillable. The viewport lives inside the block definition, same as the 11X17 sheet. Bails if the layout already exists.

C# payload

// Create the 17X11 landscape layout and insert SS_BLOCK_17X11.
//
// The block carries its own border AND its own viewport (that is how the 11X17 sheet is built -
// the viewport lives inside the block definition), so the layout only needs the block insert.
// The 11X17 sheet inserts its block at (10.81, 0.29); the block is right-anchored at x=0 and
// grows in -X, so the insert point is the sheet's RIGHT edge. For a 17-wide sheet that is
// x = 17 + a small margin, matching the portrait sheet's 0.29 bottom offset.
