Scale Genome Assembly Page for Comparative Genomics

This will likely need refinement, sub-issues as the need becomes clearer.

## Summary

As we prepare to ingest large numbers of assemblies per organism, the current curated, hand-picked list won’t scale. We need to redesign ingestion, storage, and UI to support large datasets while keeping the experience fast and discoverable.

## Motivation / Problem

- Performance will degrade if we try to render giant lists or naive queries.
- Users won’t be able to find relevant assemblies without meaningful filtering/sorting.
- Comparative genomics workflows will need broad coverage per organism, so manual curation is no longer viable.

## Goals

- Automate pulling bulk assemblies per organism (no hand-curation).
- Ensure backend/API can return paginated, filterable assembly data quickly.
- Keep the “featured reference” experience for curated genomes while exposing the larger pool for workflows.
