API Client Connector Detail Page UI issues

The API client connector detail page needs to be updated. After PF 4 migration and some other changes, it's not rendering properly. See screenshot.

Work to be done:

• Unify the page elements like in other parts of the app
• Show imported operations (need to discuss with UXD whether operations should be visible, or simply the number as it shown now)
• Disable editable fields, only enable when user selects Edit
