Monitor Type Indicator Icons

### 📑 I have found these related issues/pull requests #443 This is for service favicons. ### 🔖 Feature description I often have several types of monitors for the same host machine: Ping, TCP:22, HTTPS. I've ended up writing text for them to differentiate. I was thinking that it would be nice to have some visual indication of that in the form of a small icon depicting the monitor type. Combining with #443 for http(s) that could be the site favicon, but for ping, tcp, etc it could be a static icon that comes with the program. ### ✔️ Solution Icons somewhere on the left of the monitor pane, probably left of the percentage. Need to find/develop icons for the basic types. ### ❓ Alternatives _No response_ ### 📝 Additional Context _No response_
