Users should not have access to view all machine IDs on web UI

[Snuupy]

Describe the bug

Currently users can view all machine IDs even if they should not have access to them. Although machines are protected with passwords, this still exposes metadata that should not be exposed, leaking information (though hopefully your users are not your adversaries!)

This also applies to the groups tab in the rustdesk app.

Describe the environment

Not relevant, but docker compose, latest

How to Reproduce the bug
Steps to reproduce the behavior:

1. create a normal non-admin user
2. browse devices page, see all devices listed

Expected behavior

only devices for that individual user should be listed if they are not an admin

Additional context

N/A
