Multiple fixes for operator-ui (#948)

- fix: create tenant from operator-ui was broken due to migration from
  standalone console to embedded console
- fix: refresh, activate and attach license in subscription page was
  broken
- fix: tenant usage report in operator-ui
- fix: show tenant encryption enabled if MINIO_KMS_SECRET_KEY is present
