Unneeded access rules in the Approvals app were removed because the same permissions are already handled by an existing rule. This reduces duplication and helps keep access management easier to maintain without changing normal user workflows.

This will remove unnecessary access rules as they are already covered by another rule.

Task: 3786622

The point-of-sale IoT customer display code was cleaned up after the customer display was moved into its own dedicated app. This reduces duplicated functionality and helps keep the point-of-sale IoT module easier to maintain without changing the intended customer experience.

In the corresponding community commit we refactor the customer display into it's own module. In this commit we remove the code that is no longer needed, because it is replaced by said customer display module

Appointment publishing can no longer be managed from the backend form or Kanban views. This simplifies the backend interface and helps ensure publishing is handled through the intended website flow.

This PR removes the functionality of publishing the appointment from the backend.
- Remove the publish unpublish button from the appointment.type form view.
- Remove the publish toggle button from Kanban cards.
