"""Centralized TA-ATS seeder — runs every seeder in the correct order.

This is the single entry point for seeding. It runs `manage.py migrate` first,
then each seeder script in this folder in dependency order.

Usage (from the backend/ folder):
    ./venv/bin/python master_seeder/seed_all.py              # core seed (menus, perms, master data)
    ./venv/bin/python master_seeder/seed_all.py --with-demo  # also seed demo clients/JDs/candidates

Settings: honours DJANGO_SETTINGS_MODULE if already exported (e.g.
`export DJANGO_SETTINGS_MODULE=config.settings.prod` on the server),
otherwise defaults to config.settings.dev.
