C3D-0089 · Write the ARC/CHD/RAD format into CURVE DELTA OFF [MK-CURVE-STYLE4] error

The previous run matched components by name and missed, because the source component is Distance & Radius while the new style inherited Standard Distance and Radius. Writes the exact ARC/CHD/bearing/RAD template into the non-tag text component. No erase; verifies the contents afterwards.

C# payload

// Put the ARC/CHD/bearing/RAD format into "CURVE DELTA OFF".
//
// Last run matched components BY NAME and missed: the source calls it "Distance & Radius"
// (ampersand), the new style inherits Standard's "Distance and Radius" (word). So the format was
// never written and the style still emits L=..., R=...
//
// This writes the format template LITERALLY - the exact string read from the source in C3D-0083 -
// into whichever text component is not the Table Tag. No name matching, no CopyFrom, NO ERASE.
const string DST = "CURVE DELTA OFF";

// verbatim from "Delta over Length and Radius" / component "Distance & Radius"
