feat(visual): refine OFDM constellation display layout

- add Device Info table with standardized labels and N/A-safe sysDescr mapping
- simplify top header to centered OFDM Constellation Display title
- add Channel Summary table above scatter plots with color-coded Soft/Hard headers
- move channel identification out of overlays and center per-tile channel labels above each plot
- remove decorative grid and I/Q axis labels to reduce visual clutter
- rebalance plot margins and center tile rows for partial channel layouts (including 5-channel cases)
- increase visibility of plot/tile boundaries with lighter white borders
- regenerate visual docs/previews for GetCapture-ConstellationDisplay - 2026-02-22 22:17:44
