fix(KiCad API): 🐛 new categories excluded from simulation

[lukas-runge]

Hi @jbtronics,

first of all - thank you for developing and maintaining this incredible piece of software. 🙏

When initially adding all my parts to Part-DB with the defaults provided, I just discovered that categories get created with excluded_from_sim set to true. When also creating all parts with the default of null (which means inherit from category) then all parts are per default excluded from simulation when adding them to KiCad via the API endpoint. This means that in older versions of KiCad (pre v9) newly placed parts are initially shown crossed out

and in newer versions (v9 and newer) they get outlined and shown with an additional tag on the bottom right side

indicating that they are excluded from simulation.

This is rather annoying as changing this now requires manual adjustment of that setting for every single category in existence. This could only be made easier for existing users by providing some kind of batch editing feature which as far as I know is not a thing.

To at least mitigate this inconvenience for new users and new categories that existing users create, this PR proposes to set excluded_from_sim to null for new categories and default to false in the helper function if the property is not set.

Best regards,
@lukas-runge

I would not really call it a bug, but sounds reasonable to change the default behavior here.
Thanks.
