Fix: Machine Identities user experience improvement

[varonix0]

Description 📣

Previously we've been getting a lot of bug reports from people mixing up the identity ID and client ID, which is very understandable since we display the ID of the identity on the identity row. The ID's are both UUID format, which makes it even easier to mix them up.

In this PR I've introduced a new dropdown menu where the "Delete identity", "Update identity", and "Copy internal ID" now lives.
