Feature Request: Support for UI "Views" with Filtering (tags / monitor type)

**Is your feature request related to a problem? Please describe.**
When managing multiple monitors, the UI can quickly become cluttered and difficult to navigate. It’s frustrating not being able to group or filter monitors in a way that fits specific workflows.

**Describe the solution you'd like**
An option in the UI to create custom "views" that allow filtering monitors by tags and/or monitor type. These views would make it easier to organize and focus on relevant monitors.

**Describe alternatives you've considered**
- Manually tagging monitors and visually scanning for them (inefficient).
- Running multiple instances of peekaping for different groups (overhead and unnecessary duplication).

**Additional context**
A "view" could be saved and re-opened, similar to saved searches or dashboards in other monitoring tools.

The issue describes adding UI views with filtering by tags and monitor type. Start by exploring the frontend code for the monitors list UI and existing filtering logic. Look for tag and monitor type data structures in the backend. Understand how saved views would be stored and retrieved. A newcomer would need to understand the project's UI architecture and data flow before implementing this feature.
