FEAT: redesign GerbilIcon with a cute alert sitting silhouette and dynamic tufted tail

Utility script to clean up import data from the database after testing
/import/dry-run. Useful for re-running the import process during development
and QA. Deletes all animals and litters created by the import (identified
by ImportSource='docx-export' and ImportSource='derived-litter'), resets
sequences, and leaves the database ready for fresh import execution.
