feat(apps): enable configuring which hidden settings are available for the apps

[Gustrb]

Proposed changes (including videos or screenshots)

Enhances the server-setting.read permission, allowing it to take an array of hiddenPermissions, that are the permissions that can be searched despite being hidden (or secret). This enables us to have a Omnigateway_Url setting.

This setting is going to be responsible to have the omnigateway of the current env. By having this setting, we can easily stage our omni-apps, because, instead of having the value of the omnigateway url hardcoded, it will be just a matter of fetching the value of the setting through the apps-engine. Thus, centralizing the information
