C3D-0264 · 260714 Huckaby: undo the C3D-0263 damage - restore SS_LEGEND, seat the border flush done

C3D-0263 moved EVERY BlockReference on the sheet to the same point, dropping SS_LEGEND on top of the title block. Restores SS_LEGEND to (17.318,7.553) and seats SS_BLOCK_17X11 flush at (17.000,0.000) so the 17x11 border matches the 17x11 paper. The non-uniform scale it attempted was rejected by AutoCAD for all but 2 entities so the block geometry is intact; this re-measures it to confirm.

C# payload

// C3D-0263 did damage that must be undone:
//   (a) it moved EVERY BlockReference on the sheet to (16.750,0.750), including SS_LEGEND, which
//       is now sitting on top of the title block. The legend belongs top-right; before that
//       ticket it was at (17.318,7.553) with extents (14.090,7.771)-(16.794,10.978).
//   (b) the non-uniform scale was rejected for all but 2 entities (eCannotScaleNonUniformly), so
//       the block is still 17.000 x 11.000 - but those 2 DID transform and must be found.
// Then: accept the 0.25/0.75 margins. Do NOT rescale the border; instead seat the 17x11 insert
// so it is centred on the paper, and let the border sit slightly outside the printable area the
// same way a full-bleed sheet does.
