User story

When customizing the look and feel of the Camunda web apps, I want to change the appName and appVendor for all web apps.

Background

Customizing the Camunda web-apps is documented here: https://docs.camunda.org/manual/latest/webapps/tasklist/configuration/#logo-and-header-color (we have similar documentation for Tasklist, Admin, Welcome). For tasklist, it is already possible to customize the app name and vendor. For the webapps, this is not yet possible. The goal of this ticket is to allow this customization in all webapps.

Acceptance criteria

• Users can customize appName, appVendor for all web apps
• Users can customize welcome message and window.title for welcome page.
