test: reduce harness-e2e-cli test time (#32472)

This change optimizes the `harness-e2e-cli` integration test by migrating to the `@angular/build` application builder (esbuild), which significantly improves build performance.

Additionally, unused configurations such as Karma unit tests, SCSS support, and i18n extraction have been removed to further streamline the project and reduce dependencies.

These improvements reduce the execution time of `//integration/harness-e2e-cli:test` to approximately 38 seconds.
