ValkyrieCharacterizationService should publish file.characterized

[hackartisan]

Descriptive summary

Currently, the ValkyrieIngestJob enqueues the derivatives job directly, and enqueues the characterization job via an object.file.uploaded event.

Instead, ValkyrieIngestJob should not enqueue ValkyrieCreateDerivativesJob. ValkyrieCharacterizationService should publish file.characterized and FileMetadataListener should enqueue either CreateDerivativesJob or ValkyrieCreateDerivativesJob depending on the payload's type.

CreateDerivativesJob

Acceptance Criteria/Expected Behavior

This is a code refactor, but may fix race condition bugs if any exist when derivatives try to run before characterization is finished.
