/>

Removed the `keep your client secret at a safe place...` warning when a
auth-method without a client secret is used.
Changed the dialog title to `Client Details` instead of `Client Secret`

# Additional Changes
- Improves type safety for data passed to the
`AppSecretDialogComponent`.
- Updates the `AppSecretDialogComponent` to use modern Angular features,
improving readability and maintainability.

# Additional Context
- Closes #11834
