test: reduce harness-e2e-cli test time

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.

`wait-on` has also been updated to improve handling of server readiness.

These improvements reduce the execution time of `//integration/harness-e2e-cli:test` to approximately 20 seconds.
