Catalog:
- Re-order columns for hierarchical left-right reading
- Add source_url column for image preview
- Fix species column to include only specific epithet
- Fix scientific_name to use most specific taxonomic rank
- Filter common column to only GBIF vernacular names

Embeddings:
- Apply species and common name updates to JSON
