When the new back office UI sources where copied from former repository
I didn't realize that the .gitignore had the package-lock.json file.
This commit remove the package-lock.json file, so it can be tracked, in
order to have reproducible builds.
The lack of the file caused the build to fail due to `npm ci` requires
it.

Serve the front-end sources of the new back-office through the current
satellite admin server under the path `/back-office`.
The front-end is served in the same way than the current one, which is
through an indicated directory path with a configuration parameter or
embed in the binary when that configuration parameter is empty.
The commit also slightly changes the test that checks serving these
static assets for not targeting the empty file in the build folder.
build folders must remain because of the embed directive.

Add the front-end sources of the new back-office.
The front-end doesn't have any business logic, it only has the pages and
the components, so it's purely UI.
The front-end was developed in a separate repository until was
completed.
