fix: use self.__WB_MANIFEST literal in sw.js for workbox-build injectManifest

workbox-build does a text search for the exact string 'self.__WB_MANIFEST'
in the service worker source. Using it via an alias (sw.__WB_MANIFEST where
const sw = self) is not matched, causing the Docker build to fail with:
'Unable to find a place to inject the manifest.'

Fixes the Docker Publish GitHub Actions workflow failure.
