feat: Include imageInfo during tale copy

[craig-willis]

Problem When copying a tale (or copy-on-launch), information about the built image isn't currently included.

Approach Copy the tale imageInfo excluding jobId, since it may be owned by someone else (copy on launch).

Testing

• Create and run a tale, note the imageInfo
• Duplicate the tale, note the imageInfo is present except jobId
