jif 4f7032173e Honor filesystem permissions for app file uploads (#38416)
## Why

App tool file arguments could read and upload files without applying the active
filesystem sandbox policy.

## What changed

- Apply the effective filesystem policy, including session and turn grants, when
  reading metadata and streaming files for upload.
- Reject uploads before contacting the files endpoint when the selected path is
  denied.
- Report an error when the executor cannot provide sandboxed file streaming for
  a restricted policy.

## Testing

Added integration coverage showing that restricted policies allow permitted
files and reject denied files before upload.
