Add buildAll task and fix fragile builds (#3077)

This commit adds the buildAll task to restore the existence of a target that builds everything, which was unintentionally removed when the default build was stripped down in PR #3068. It also introduces necessary sequential constraints to the console-webapp build tasks to prevent parallel execution from corrupting the Angular CLI cache. Finally, it addresses paths for the newer Angular esbuild output and hardens the style injection in ConsoleScreenshotTest to prevent fragile test failures.
