Cross Environment Bundle Deployment

Ensure that both the environments have the same build number deployed.
In the bundle there may be use of S3 files like icons in Subject Type
- Do find in files for such data and remove it.
- Manually upload the assets from the application screen (app designer, edit subject type in this case)
Concept media (images attached to concepts) is carried in the bundle's conceptMedia/ folder, never inside concepts.json.
- If the bundle contains concepts.json, it must also contain the conceptMedia/ entries from a current export of the target org.
- Uploading concepts.json without them clears the media on those concepts. There is no error, and the bundle review diff does not show it, since concepts.json is unchanged. See avni-server#1043 — this is intended behaviour, not a bug to wait on.
There is bug in platform related to bundle upload/download for GroupPrivilege.
