ID of the source file entity in the epilot file-entity system. Set when the file was picked from the File Manager (rather than uploaded directly to the design-builder bucket). Consumers resolve the live public_url via this reference. The org id is derived from the journey's owning org at render time (same convention as journey image blocks), so blueprint cross-org installs work without any extra remapping.
