feat add source st file path to twins

[PTKu]

Summary

• Emits a new SourceFileAttribute on transpiled types so generated twin/POCO/Onliner C# carries the originating .st source file path.
• Adds SourceFileAttribute + SourceFileAttributeHelper and wires emission through the Onliner and Plain source builders; regenerates all expected unit fixtures (ax/tia/ix) accordingly.
• Adds dependency tooling: update-latest-deps.ps1, update-vulnerable-deps.ps1, shared _deps-common.ps1; pins transitive vulnerabilities and bumps Inxton.Operon / NuGet packages.
• Refactors operon-variables.css for consistency.

Note: this repository has no CHANGELOG.md, so the description is derived from commits and the diff stat rather than a changelog entry.

Test plan

• Run the modified PowerShell script(s) end-to-end and verify exit code 0
• apax build from a workspace succeeds (the src/apax/apax-lock.json + Directory.Packages.props changes resolve)
• dotnet build from solution root succeeds
• PLC code compiles via apax build; affected .st sample sequences transpile with the new SourceFileAttribute
• CsTests SourceFileAttributeTests pass and all regenerated expected fixtures match
