dev_wipe.py — Test data cleanup script for Lojiz dev/staging.

Wipes all test data for a given user ID:
  • scout_mandates
  • search_alerts
  • bookings (pending/confirmed only — leaves completed history)
  • viewings
  • notifications
  • aida DM messages + conversation clear-marker

Usage:
    python dev_wipe.py                         # wipes default USER_ID below
    python dev_wipe.py <user_id>               # wipes specific user
    python dev_wipe.py --all-mandates          # wipes ALL scout mandates (all users)
