Set SkipSpaBuild environment variable in Dockerfile to prevent MSBuild from rebuilding the frontend during publish, as it is already built in a separate stage. Also disable NuGet audit warnings to reduce build noise.
This change adds the `ignoreDeprecations: "6.0"` option to the TypeScript configuration to suppress deprecation warnings related to TypeScript 6.0 changes, ensuring a cleaner build process without breaking existing functionality.
