Fixes #220
Related: #215

Depends on #216. This branch is based on the branch of that pull request, so the diff against main contains its commit until it is merged.

Changes

• store_entity collects the category templates from the allOf chain of the meta category schemas, in the order of the wiki form editor, instead of walking subclass_of. The walk includes every entry of properties and the items of each property, after allOf, oneOf, anyOf, definitions and $defs. A referenced schema is walked only at its first occurrence.
• The definitions section mode is chosen when Category:OSWffe74f291d354037b318c422591c5023 (CharacteristicType) is in that list, not by the model class of the entity.
• Ports of the wiki post processing: the reset of the generated @context block, the merge of the generated @context into the first object block, and the removal of root members that the generated section defines.
• A warning is logged when the jsonschema of a meta category page is missing.

Rationale

Category:Category has an allOf to CharacteristicType and no subclass_of, so the subclass_of walk never reached the CharacteristicType template. The wiki follows the schema allOf.

Tests

• New regression test tests/test_store_entity_category_templates.py. It stores the after jsondata of two saved Category pages (PhysicalItem and PhysicalItemType; the repository owner stated that they were saved unchanged through the form editor, which was not verified here) on top of the before jsonschema, offline, and expects the jsonschema of the after state. Both pages are equal to the form-editor result.
• Unit tests for the template order, the walk through properties and items, the @context reset, the removal of root members and the warning.
• tests/test_store_entity_keeps_jsonschema.py now serves a meta category schema with an allOf to CharacteristicType where it expects the definitions section mode.
• Full offline suite: 815 passed.

Limits

• A /wiki/<title>?action=raw reference is followed only for category pages. For example /wiki/JsonSchema:Label?action=raw is not followed. A Special:SlotResolver reference is followed for any page.
• The @context reset, the @context merge and the removal of root members run only in definitions section mode.
• Namespaces other than Category are unchanged: store_entity generates no schema there, the wiki does.
