On macOS, `briefcase run` requires admin status

### Describe the bug

`briefcase run` can fail for users with limited access. For instance, this macbook is remotely managed and limits administrative tasks by default.

```
❯ briefcase run --log

[helloworld] Building App...
Renaming stub binary... done

[helloworld] Ad-hoc signing app...

[helloworld] Built build/helloworld/macos/app/Hello World.app

[helloworld] Starting app...
===========================================================================
log: Must be admin to run 'stream' command
```

### Steps to reproduce

Not specifically sure...but run `briefcase run` for a limited user on macOS.

### Expected behavior

The app could run without `log stream` perhaps.

### Screenshots

### Environment

- Operating System: Sequoia
- Python version: 3.12.7
- Software versions:
- Briefcase: `0.3.20.dev369+gf6b5d83f`

### Additional context

_No response_

Start by reproducing `briefcase run --log` as a limited user on macOS Sequoia and inspect the attached run log, focusing on the `log stream` admin error. Trace the `briefcase run` startup path that invokes `log stream`; done means the app launches successfully without requiring administrator access.
