Main improvement of this commit is that the reusable category button
component is used as the collapsable header component for the material
brands/types.
CURA-8979
Put content of category button in a `RowLayout` so individual content
Components can easily be removed by hiding said component while keeping
margins and spacings work as intended.
Additionaly make the icon property optional

The checkbox was still there in the preferences page, but it didn't work at all, for two reasons:
- The preference entry didn't exist. This was causing warnings in the log (which is why I saw it).
- It wasn't checking the preference before making that API call. Could make a bunch of people pretty angry.
Adding and splitting of lines results in print artefacts and additional travel moves. Avoiding these by sacrificing some additional line width change is better. The linewidth can never very more then 75% - 150%, so this long filter distance cannot cause huge line width changes. PP-129
The top bottom is a 100% density part of the print. For these parts it is super important to not over extrude. At the same time we dont want an underextruded top layer, since that is looking ugly. That is why we enable a roofing layer and reduce the flow for the rest of the top/bottom. PP-93
The parent settings have default values, which come out to different values than the old ones
when using the "value" function formula.
This commit sets the default values at the values as they are calculated from using 0.4mm line widths and 0.3mm min line widths.
The formula in that setting means that this setting was always the same as the Min Odd Wall Line Width,
but that is not really a natural value for this setting.
The absolute minimum for a line is generally known to be 75% of the nozzle size, so we use that instead.
Doesn't solve all of the issues here, but at least fixes it for english.
I feel that the word guide also doesn't actually add any meaningfull info anyway
