Support auth tokens via API

Suggestions on auth tokens: https://gitlab.com/pheix-io/service/-/tree/requirements/docs#user-accounts-management

Keep in mind:

• some API routes could be public and should be available without auth/tokens (as I can see, quick way to do this is to use static content or guest token for such kind routes);
• some routes could have a valid token but fails on node auth, so this case is extremely curious (should be tested at least).
