UI scaling factor does not adjust when screen disconnects

### Apache NetBeans version

Apache NetBeans 27

### What happened

After disconnecting the external monitor, NB is moving to the laptop screen, and nothing is readable due resolution.

Floating windows after moving NB to another screen (external) is displaying on the origin screen.

### Language / Project Type / NetBeans Component

_No response_

### How to reproduce

After disconnecting the monitor and moving NB to the laptop screen, recount resolution the same way as after restarting NB app.

The best behavior for floating windows could be similar to "find in project" window.

### Did this work correctly in an earlier version?

Apache NetBeans 27

### Operating System

Linux/Ubuntu

### JDK

javac 25

### Apache NetBeans packaging

Apache NetBeans Snap Package

### Anything else

_No response_

### Are you willing to submit a pull request?

No

Start by reproducing the monitor disconnect and screen-move scenarios described in the issue on Linux/Ubuntu with the Snap package. Investigate how NetBeans recalculates UI scaling and repositions floating windows across screens; done means readable UI scaling after disconnection and floating windows appearing on the active screen.
