P1 UI polish: clear engineering estimates, header breathing room, and actionable empty states

[masarray]

User screenshot findings / changes

• Header: remove redundant Workspace wording, left-align workspace pills and enforce 20-DIP separation from the network-adapter dropdown.
• Measurements: replace misleading UNVERIFIED badge with quiet Nominal scale labeling. Preserve the existing scaling tooltip, engineering scale control and capture footer caveat. No false claim of SCL calibration.
• PTP diagnostic clock lock: NOT MEASURED and packet observation explanation replaces the ambiguous UNVERIFIED (received PTP traffic is not proof of clock lock).
• P1 visual consistency: 16/14 DIP hero/panel padding, unified inspector border and more subtle 9-DIP section-card radius.
• GOOSE: concise no-event copy with capture-path caveat on hover; no blank publisher/network/dataset cards until an event is selected; show one actionable empty-state hint instead.
• SCL: suppress three huge blank engineering tables when no SCL is loaded; show one centered concise import instruction; previously loaded stream catalog, binding matrix, full dataset and technical evidence retained.
• No SV decoder, phasor or timing math modifications.

Keep the workspace rail clear of capture controls

At the default 1600-DIP window width—and more severely at the 1240-DIP minimum—the seven fixed-width workspace buttons require about 990 DIPs, but this star column receives only the space left after the product identity and roughly 560-DIP capture-control stack. Changing the rail from centered to left-aligned pushes its overflow entirely into column 3, where the later-declared adapter and run controls render and hit-test over the Validation and Advanced buttons. The new margin on the capture stack further reduces the star column rather than reserving space after the rail; this needs responsive button sizing/wrapping or a layout that actually allocates both groups their required widths.
