Feature Request: Apps with no web interface

[loficafe-zx]

I am working on a new app submission that sets up dockurr/samba for Umbrel. However, this container lacks any kind of user interface. To address this, I added a simple HTML page to avoid having a clickable icon that doesn't open anything.

In the future, I could implement a feature allowing users to edit their settings on a webpage. However, I believe it would be beneficial to have dedicated implementations within Umbrel OS for this type of app. Here are a few suggestions:

• Right-Click Options: Introduce a new option for right-clicking on the app icon that opens a text editor for predefined configuration files. This editor would allow users to restore settings to their defaults.
• Non-Clickable Icons for Apps Without Ports: Modify the behavior so that apps without a port specified in their umbrel-app.yml are not clickable.
• Credential Display: Change the 'Show default credentials' option to 'Show credentials' for relevant apps.

These implementations would improve user experience and provide better functionality for apps like Samba and open a new world of possibilities for apps.
