Assigned IAM profile doesn't show up

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 26.5.1 (25F80)

### Expected behaviour

I have two assigned profile in my Enterprise IAM identity center, I would expect it to be able to switch between them.

### Actual behaviour

Only one profile (the old one) is available via `kiro-cli profile`. The other one shows up on Kiro web or Kiro IDE, but when I select it I get `Access denied`

### Steps to reproduce

_No response_

Inizia riproducendo l'elenco dei profili con `kiro-cli profile` dopo aver eseguito `q doctor` e `q restart`, utilizzando i due profili Enterprise IAM Identity Center indicati. Confronta il risultato della CLI con il profilo disponibile in Kiro web o IDE; il lavoro è completato quando entrambi i profili assegnati sono selezionabili senza `Access denied`.
