fix: extend remote compute image path conversion to all node types

Previously only the "path" field was converted to a relative path for remote computes, causing issues with QEMU and VMware nodes that use different image path fields. Now all known image path fields are converted, ensuring consistent behavior across IOU, QEMU, Dynamips, and VMware node types.
