C3D-0254 · 260714 Huckaby: fix the 17X11 sheet - viewport view, missing notes, media, stray viewport, insert position done

Repairs the five defects the audit found. (1) The viewport was showing 1inch=9876feet at coordinates far off site because ViewCenter/CustomScale were assigned to a LOCKED viewport - now unlocked, ViewHeight set first then center, then relocked. (2) Copies the sheet furniture from 11X17 (property-lines note, UPC dig block, field closure, GA W.GRID, vicinity label, SS_LEGEND) shifted +6.5 in X for the landscape aspect, rejecting anything that lands off-sheet. (3) Prefers a true 17x11 media over the generic ANSI_full_bleed_B forced landscape by rotation. (4) Erases the inert viewport left inside the block definition. (5) Reseats the block insert so it stops overhanging the sheet top.

// Repair the 17X11 sheet. The audit (C3D-0253) found five defects:
//   1. VP#2 view is (2089122,1226671) h=80462 -> 1"=9876'. Nowhere near the site. Setting
//      ViewCenter then CustomScale on a LOCKED viewport re-derives the view, so it must be
//      unlocked, set height+center, THEN locked.
//   2. The sheet has 3 entities; 11X17 has 141. Every sheet note and the legend block are missing.
//   3. Media is the generic "ANSI_full_bleed_B" (11x17 portrait) forced landscape by a 90 deg
//      plot rotation. Prefer a true 17x11 media if one is registered.
//   4. A stray viewport is still inside the SS_BLOCK_17X11 definition (inert but wrong).
//   5. The block insert runs to y=11.290 on an 11.000 sheet - drop it to sit inside.
