…tor UI fixes (elastic#156629)

## Summary

This PR addresses adding safeguards to the 'block' action around FIM
capabilities in D4C (cloud_defend)
see: https://github.com/elastic/cloud-defend/issues/337

It also fixes a few bugs:
1. updates not being reflected in the yaml editor side when changed on
the UI side (after yaml editor viewed for first time).
2. the yaml -> json conversion function was mutating the original
selector/response when deleting the type property. which would cause the
item to dissapear under certain situations.
