Add Wiremock mappings endpoint to dev ui card (#180)

Adds a first entry to the Wiremock dev ui card by pointing to the Admin API, see https://wiremock.org/docs/standalone/administration/

This is first addition to the dev ui for Wiremock, we could potentially think about adding some more useful things here.
