Show identity alias in identity overrides list inside feature detail

### Is your feature request related to a problem? Please describe.

We currently support identity aliases to provide human-readable names for identities that might otherwise have meaningless IDs. These IDs are used in the identities list and details, but not in the list of identity overrides inside a feature (`foo` here is an identifier, not an alias):


### Describe the solution you'd like.

If an identity has an alias, show it inside this page the same way we show it elsewhere.

### Describe alternatives you've considered

🤷
