C3D-0167 · Reload SS_BLOCK_11X17 from the block file + refill attributes [RELOAD-BLOCK-260714] done

Replaces this drawing stale SS_BLOCK_11X17 definition with the updated one from SS_BLOCK_11X17.dwg using a side database and WblockCloneObjects with Replace, so the existing insert keeps its position, then rebuilds each insert attribute collection from the new definition and fills every value for job 260714 including FIRM_PANEL 13113C0155E, FIRM_DATE September 26 2008 and FLOOD_ZONE X.

C# payload

// Replace this drawing's stale SS_BLOCK_11X17 definition with the updated one from the block
// file (which now carries the flood note + FIRM_PANEL / FIRM_DATE / FLOOD_ZONE attributes), then
// refill every attribute for job 260714.
//
// Method: read the block DEFINITION out of the source drawing with a side database and
// WblockCloneObjects with DuplicateRecordCloning.Replace - that redefines the block in place, so
// the existing insert keeps its position and simply picks up the new definition. Safer than
// erase + purge + re-insert, which loses the placement.
//
// Attribute values come from GET /api/project-by-id?job_number=260714 plus the FEMA fields:
//   firmPanel 13113C0155E | firmPanelDate 09/26/2008 | floodZone X
//
// Only SS_BLOCK_11X17 is touched.
