Server-side copy of one B2 object to a new name, within the same bucket or
across two buckets in the same account.
The copy is done by reference (b2_copy_file for small, b2_copy_part for
large): bytes never traverse the runner. This is dramatically faster and
cheaper than download-then-reupload for any non-trivial file.
Cross-bucket: set source-bucket to the source bucket name. The action's
bucket input is the destination. The application key must have read
permission on the source bucket and write permission on the destination.
