"""
|

Wipes the POS database completely and re-applies the schema + default seed data.
|
||||
|
||||
Usage:
|
||||
python wipe_database.py
|
||||
|
||||
Safe to run even if the backend is stopped. Does NOT delete the .db file —
|
||||
it drops all tables and recreates them so the file path stays intact.
|
||||
After running this, run demo_seed.py to populate with demo data.
