fix(base): Use Build Time Base Path

* If a base path is provided at build time, use it.
  * Base path can be set with `VIKUNJA_FRONTEND_BASE` at
    build time
    * `VIKUNJA_FRONTEND_BASE` sets `import.meta.env.BASE_URL` after Vite resolves it.
    * Usages of `import.meta.env.BASE_URL` are statically replaced
      at build time.
    * If base path is not provided, `import.meta.env.BASE_URL`
      defaults to '/'.
    * Documentation:
      https://vitejs.dev/guide/env-and-mode.html

* Fixes:
  * Manifest not loading because of incorrect path.
  * Service Worker not loading because path is incorrect in
    manifest.
  * Service Worker crashing because import of workbox is from
    wrong path.
  * Service Worker not loading a task because path is incorrect
    in event listener.
  * Incorrect URLs being set on window because base path is
    incorrect.
    * ex: `/login` vs `/base/login`
