GUI redesign - the elements are too large and such big cards don't bring value

**Describe the problem you have/What new integration you would like**
Having around 100 devices, it appears on 4 pages while it could be on 1 or 2

**Please describe your use case for this integration and alternatives you've tried:**
The cards for devices have just 3 buttons - why do we needs such big cards?.

**Additional context**

The issue names no files, tests, or entry points. Start by locating the GUI device-card and pagination implementation, then establish the intended compact layout and verify that roughly 100 devices can be browsed across fewer pages without losing required controls.
