TechDraw: GeometricHatch does not enable scale smaller than 0.1 during hatch creation

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Problem description

Steps to reproduce:

- open file (remove the .zip extension)

[FC-scale-testing .FCStd.zip](https://github.com/user-attachments/files/19895718/FC-scale-testing.FCStd.zip)

- select the face on the page
- start T`echDraw_GeometricHatch`
- set `Scale` to 0.01
- the Scale gets set back to 1. It is not possible to set the value lower than 0.1

See behavior in the video:

https://github.com/user-attachments/assets/8c7ad71a-d819-421d-8c79-91906083b7e3

**Expected behavior:**
The Scale value should be possible to be set to the smallest decimal value available in the dialogue

### Subproject(s) affected?

TechDraw

### Anything else?

There is a possible workaround: create the hatch with Scale set to 1 and than change the `Scale` value in the properties of the hatch.
