feat: populate included_presets at publish

In create_associated_file_objects, set each renderable (non-supplementary)
file's own-preset bit (2 ** RENDERABLE_PRESETS_ORDER.index(preset_id)) and
leave supplementary files NULL. A preset missing from the append-only
ordering is logged and skipped rather than aborting the channel publish.
