iPhone 13 Pro Max ProMotion Support

[bandundu]

Describe the bug The app does not support ProMotion and it's higher refresh rates which makes the UI feel sluggish for newer devices.

To Reproduce Steps to reproduce the behavior:

1. Use a device with ProMotion support e.g. iPhone 13 Pro Max
2. Open the Paperless App
3. Scroll through the UI
4. Notice low refresh rate

Expected behavior The display should use higher refresh rates while scrolling and automatically scale down the refresh rate when reading.

Additional information Do you use Paperless NG as a backend: Yes

Apparently this has only been implemented in Flutter recently: https://github.com/flutter/flutter/issues/90675#issuecomment-1087793695

This should be easy enough to do.
