Improve stability of custom metadata

1 Initial Problem

We often have problems with the Custom Metadata used in Wikis to generate page lists of wiki entries. The lists do not always collect the correct pages. This makes it difficult to use this helpful feature.

2 Conceptual Summary

The implementation of (Multi-)Select Custom Metadata fields should be improved.

An ordering parameter for options (separate from their ID) should be introduced.

In the course of this, the handling of options should the reworked according to the repository pattern, complete with the introduction of data objects.

Further, testcase coverage for the editing of options of (Multi-)Selects (reordering, deleting options, adding new options), especially in interaction with page lists, should be improved.
