Integrate with Matomo

[holtgrewe]

Is your feature request related to a problem? Please describe.
We need Matomo usage tracking.

Describe the solution you'd like

• Enable by defining MATOMO_HOST and MATOMO_SITE_ID configuration variables.
• Expose this to the frontend through a "frontend-settings" endpoint in the API.
• Create new api/ for this and stores/ file.
• Read settings in frontend and interpret.
• Configuration settings differing from defaults
  • requireConsent: true
  • disableCookies: true
• We should first try to disable cookies.

Describe alternatives you've considered
N/A

Additional context
Ideally, we can do this from vite directly. In the worst case, entrypoint could modify the index.html page from the environment that is used when running the server. It is important that this is not baked into the Docker image but part of the environment when running.
