A separate vitest.config.ts keeps the tests off the build
plugins and the mediapipe version check in vite.config.ts.
make test now runs the frontend tests after the backend ones,
and test-front runs on Node 24, the current LTS.
Configured the frontend to use environment variables (prefixed with "VITE_") for frontend
port and host configuration, which will be overridden in the Helm chart values
to ensure correct values are used in different environments.
Helm requires the frontend port to be 8081 and use the public host,
not the default "localhost" value.
Update frontend to be the root folder of the frontend sources,
instead of nesting them in a folder named as the application.
We only work on a single frontend app as of today, nesting
sources doesn't add any value, even though the initial organization
was more extensible.
