Fix SCL mismatch clipping and prepare v1.4.0 stable public release

[masarray]

Operator repair

• Natural-height SCL binding rows and sufficient status badge width for MISMATCH and other verdicts; score remains accessible on hover without repeating clutter on every row.
• Wrapping of expected/observed svID in constrained Grid cells (not unconstrained StackPanel), no arbitrary character truncation; reduce the binding matrix to Status, Expected svID, Observed svID, Difference. Typed dataset and full evidence preserved in inspector.
• Remove redundant SCL caption, verification label, and technical acronym line that duplicates dataset columns.

Stable release preparation

• Set proper 1.4.0 version (optional suffix remains supported for future betas), update README and publish release notes docs/RELEASE_NOTES_v1.4.0.md.
• Stable describes the packaged software—not certified IEC 61850 timing, protection operation or metrology. Existing hardware/DPI acceptance limitations remain clearly disclosed.

Gates

• .NET Windows Release build + regression tests
• Runtime stability / architecture gates
• CodeQL and dependency review
• Portable win-x64 candidate, SHA256 manifest verification
• Public stable v1.4.0 GitHub Release only once all gates pass.

Synchronize release metadata with the stable version

Changing the repository version to 1.4.0 makes the repository-health step in .github/workflows/ci.yml fail deterministically because docs/index.html still declares 1.4.0-beta.2 and the README still uses the beta.2 package name; the release workflow also defaults to beta.2 and marks manual releases as prereleases. Update these required version consumers together so CI can pass and the stable workflow cannot publish the old beta package.

Preserve protocol identity in the mixed binding matrix

SclFilteredBindingMatrix contains both SV and GOOSE rows, but this change removes the Protocol column and labels every expected identity as an svID. When GOOSE bindings are present, their goID/GoCBRef values therefore appear under an incorrect svID heading and operators can no longer distinguish otherwise similar SV and GOOSE rows; retain the protocol column or use protocol-neutral/dynamic identity headings.
