Issue Summary

When forge tunnel is in use, local images in UI Kit will not be able to be displayed, due to not passing the egress permissions check:

Egress permissions for http://localhost:8000/721a79162300f778.. missing in the manifest. For more information see reference docs

Steps to Reproduce

1. create a forge UI Kit app
2. import a local image (see this example snippet])
3. deploy and install the app in the default development environment
4. run forge tunnel

Expected Results

There should be no additional permissions required for local images.

Actual Results

Image will not be displayed, egress warning will show up instead.

Workaround

• The workaround is to not use forge tunnel (i.e., manually deploy the app to see changes)
