Resolve IED capability and fault-record regressions

[masarray]

Summary

Ports the still-relevant fixes from stale draft PR #49 onto the current main branch without carrying its outdated history or conflicts.

Fixes

• Marshals capability-state refreshes through the owning IED card dispatcher before touching WPF controls.
• Verifies the card is still loaded and bound to the same IED before applying an asynchronous refresh.
• Moves GOOSE, SMV, and File Transfer actions into a dedicated card row so they cannot cover lifecycle buttons.
• Makes immutable Fault Record labels explicitly OneTime.
• Makes display-only state and DataGrid bindings explicitly OneWay.
• Keeps only editable directory fields and record selection as TwoWay.
• Adds a source-validation guard that prevents implicit binding-mode regressions.

Why replace #49

PR #49 is an old conflicting draft based on a much earlier main. Its substantive fixes were not fully present in the current branch, so they were re-audited and ported here as a compact current-base change set.

Validation

• source and licensing boundaries
• explicit Fault Record binding modes
• UX, GOOSE, and SAS invariants
• ARIEC61850 compatibility
• .NET restore and Release build
• portable x64 publish and artifact upload
