### Description

I have a laptop , the night mode only affects the external monitor , but not the laptop's eDP

### Expected Behavior

_No response_

### Steps to Reproduce

1. turn on the both outputs in niri conf
2. turn on the night mode from control center

### Error Messages/Logs

_No response_

### Screenshots/Recordings

_No response_

Reproduce the issue with both outputs enabled in the niri configuration, then toggle Night Mode from the control center and compare the external monitor with the laptop eDP display. Start by tracing the Night Mode display-handling entry point in DankMaterialShell; done means the mode applies consistently to both outputs.
