build: refactor frontend build

* Always write ESLint output to a file in addition to the console to make the
  lintFrontend task cacheable in Gradle (according to the output file).
* Make sure frontend task inputs are declared properly for caching.
* Make sure Typescript type checking is incremental.
* Do not use @tsconfig, because both Vite and SonarScanner have problems with
  extending tsconfig files from Yarn PnP modules.
