ENH: Allow sorting of properties

Summary

For https://gitlab.indiscale.com/caosdb/customers/leibniz-zmt/management/-/issues/140. Adds the possibility to configure the order in which the properties of (Records of) a defined RecordType are shown.

Focus

Test Environment

New unit tests should be more or less sufficient. Also test this manually, e.g. by using the demo profile, enabling BUILD_MODULE_EXT_PROPERTY_DISPLAY, and adding the following to your conf/ext/json/ext_prop_display.json:

{
    "MusicalInstrument": {
        "order": ["Photograph", "electric"]
    }
}

Make sure that all properties of all instruments are displayed in the correct order, and that properties that are not part of the order list are appended.

You may also want to verify that the feature does not interfere with the hiding of properties.

Also check whether the new documentation is understandable.
