C3D-HCWA-MHFIX · HCWA fix: symbolize 2 missing manholes done

10 SSMH points were surveyed but only 8 drawn. Adds circles + text for #101 and #102 (HCWA requires every manhole symbolized). Line 4 terminates on #101.

C# payload

// HCWA fix: 2 surveyed manholes (#101, #102) have no drawn symbol. HCWA requires every manhole
// symbolized with a circle centered exactly on the tangent endpoint. Adds them at r=2.00 to match
// the existing 8, plus their SEWER_MANHOLE_TEXT labels. Idempotent.

Result

  added SSMH #102 'SSMH MD 13.96 WATER' @(2296981.39,1279913.29) r=2.00 layer=SEWER_MANHOLE (verified)
MANHOLE SYMBOLS ADDED: 2. All surveyed SSMH points are now symbolized.
