C3D-0246 · 260714 Huckaby: trim the leftover right-edge segment in SS_BLOCK_17X11 done

Erases 20E4A, the redundant right-edge segment left at the old sheet height (13.765-16.477) which held the block extents at 16.477, and clamps the remaining right-edge line to terminate at y=11.000. Verifies the block is 17.000 x 11.000 on read-back.

C# payload

// SS_BLOCK_17X11: the right outer edge was three stacked segments (0..6.883, 6.883..13.765,
// 13.765..16.477). The first two were remapped, but 20E4A had BOTH endpoints above the panel so
// the remap left it at the old sheet height, holding the block extents at 16.477.
// The right edge only needs to reach the new top (11.000), so this segment is redundant - the
// two below it already cover 0..13.765. Trim it to close the corner at 11.000 and no further.
