Search input changes race condition

When we enter some value to search input on first view (with Content types list) and after that we change it again but previous triggered request doesn't complete the latest value'll be changed to the first (to that value which started the first GET request).

Propositions to solve this issue:
- add spinner + disable inputs (search and dropdowns) when loading (you can try to use useNavigation hook from react-router)

Start at the first view containing the Content types list and trace the search input through the GET request, reproducing the issue by changing the value before the first request completes. Review the suggested useNavigation hook from react-router; done means an earlier request can no longer replace the latest search value, with loading behavior matching the issue's proposal.
