C3D-INSP2403B · Full VP-freeze + parcel-layer map (read-only) error

Per-viewport frozen-layer sets for 09/10/R4, and the layer each parcel + its area label sits on. For heroing Parcel #2 (1.593 ac) on paper 10.

C# payload

// - each paper tab: for each non-paper viewport, list ALL per-VP frozen layers (full, not sampled)
// - Parcel #1 and #2: their layer, the layer of their area label, and their boundary segment count
