Suggestion: Allow Custom VPS Icons in Dashboard

Currently, the Webdock dashboard automatically assigns an icon to each VPS based on the associated domain. However, this system has a limitation: it only uses the main domain (e.g., it grabs the icon for pp.com instead of example.pp.com). As a result, users may see an icon that doesn't reflect their actual service or brand.

It would be great to have an option to manually change the VPS icon in the dashboard. Alternatively, improving the current favicon-fetching system to correctly detect subdomain icons would also solve the issue.

Adding this small feature would enhance customization and give users more control over how their servers are represented.
