C3D-0076 · Restore the two N/A slope labels I overwrote, fix 2EC8E length [REPAIR-LABELS] done

C3D-0075 treated any label without a percent sign as a length label, so the N/A slope labels on 2EC87 and 2EC88 were overwritten with the line length. Restores handles 2EF5E and 2EF5F to N/A and rewrites the 2EC8E length label that was skipped. Targets by handle, verifies each before writing.

C# payload

// Repair my own bad rewrite in C3D-0075.
//
// BUG: I treated "any label without a % is a length label". "N/A" has no %, so the N/A SLOPE
// labels on 2EC87 and 2EC88 got overwritten with the line length. Those two lines now show their
// length twice and have no slope label.
//
// Fix: 2EF5E and 2EF5F are addressed BY HANDLE (not by any heuristic) and set back to "N/A".
// Also 2EC8E's length label was skipped last run and is still stale - rewrite it from the line.
//
// Handles come from the C3D-0075 run log; each is verified to be the expected MText on
// SEWER_LINE_TEXT before it is touched, and aborts if it is not what is expected.
