fix: add ability to set Auth token on prod manually using local storage

Description

Motivation: As a developer I want to have ability to set manually Basic Authorization token using localstorage to have easy and quick access to OCM-Engine Dashboard

When it will be useful: Just for debugging deployed OCM Engine which does not have credential definition which can be used as a login credentials

Developer can set manually some value to OCMENGINE_AUTHORIZATION localstorage key, and this value will be used in Authorization header
