Segment celery queues

**Overview**
Right now all celery jobs go into the same default queue, which makes it hard to set thresholds or troubleshoot when the queues get too large. We want to segment jobs into more informed / targeted queues to give us more control over the situation.

**Acceptance Criteria**
- Identify relevant segments and categorize celery jobs into new named queues

**XD Links:**

**Tech Details:**
- Some suggested segments are donations + CLR calcs (high-use jobs)

**Open Questions:**

**Notes/Assumptions:**

No files, tests, or entry points are specified. Start by locating the existing Celery job and default-queue configuration, then inventory the jobs and define meaningful queue segments, including donations and CLR calculations; done means relevant jobs are categorized into named queues.
