Use data bucket as ingest bucket

### Background

Right now there are some parts of the ingest system that have access to the ingest buckets but not explicitly the data bucket.

### Description

We'd like to be able to use the table buckets as ingest buckets.

### Analysis

We could go through all the usages of IngestStack.addIngestSourceBucketReferences and replace them with something that can model the fact that the table buckets should also count as ingest source buckets.

Some of those places may also set permissions for the table buckets explicitly, so we need some way to handle that.
