Refactor Axios usage in modules/SearchFilterSettingsModule.ts to REST Module

[edalex-ian]

Is your feature request related to a problem? Please describe.

modules/SearchFilterSettingsModule.ts has a number of direct Axios usages which should be moved to the REST module (oeq-ts-rest-api).

Describe the solution you'd like

• Create SearchFilterSettings.ts in REST Module with the functions:
  • getMimeTypeFilters
  • batchUpdateOrAddMimeTypeFilters
  • batchDeleteMimeTypeFilters
• Update SearchFilterSettingsModule.ts to use the REST Module functions

Additional context

here are a number of modules that require this, each will have its own ticket.

There is some interesting overlap here with the batch operations also found in the FacetedSearchSettingsModule - see #2624 . Whether some consideration needs to be given to that in the REST module I'm not sure.
