Draft: remove owner key from the query

• All the functionality of the EncyclopediaNormalizer is now integrated into ResultsNormalizer.
• Updated materia to support visualizing 2D and 1D cells that may have zero-length basis vectors. With this update, the overview page now also shows the conventional/primitive cell for 1D and 2D systems.
• Fixed issue with the ordering of basis vectors for conventional/primitive 1D and 2D structures. Now the order is fixed so that the periodic bases always come first.
• Migrated test_encyclopedia.py into test_material.py, test_method.py and test_properties.py. together with a few new tests.
• Removed the Encyclopedia GUI image dependency and docker build phase.
• Removed most Encyclopedia related config from nginx, helm and config.py. The only remaining config is encyclopediaEnabled, which activates/deactivates links to the material search and material-related links.
• Fixed issue where the optional nmd-prefixed Optimade data was not accepting data with unit information (ureg.Quantity) and was failiing when trying to serialize data set to None.
