Feature Request:Add keyboard height/width resize handle

[wrn491]

Description:
Hi LeanType team,

I love using LeanType. It's clean and lightweight.

Request:
Can you please add a "Resize" option/handle for the keyboard, similar to what Florisboard has?

In Florisboard, there is a resize button/handle on the keyboard. By long-pressing and dragging it, users can adjust the keyboard height and width to fit their screen and preference.

Why this is needed:

1. Better one-handed use: Users with smaller phones can make the keyboard smaller.
2. Accessibility: Users with bigger screens/tablets can make it taller to reduce typos.
3. Customization: Everyone has different thumb reach. This gives full control.

This one feature will make LeanType 10x more comfortable to use daily.

Thank you for building such a great open-source keyboard 🙏
Looking forward to this feature.
