fix_listing_6a0b82_geocode.py
=============================
One-off data repair for listing 6a0b82f081458f7caa129dd8.

Background: a vague neighborhood ("AGLA", a district of Cotonou, Benin) was
geocoded — before the geocoder was hardened — to Општина Тител, Србија
(lat=45.19, lon=20.09), and the currency was derived as RSD instead of XOF.

This script re-runs the *fixed* geocoder for that listing's location and
corrects latitude/longitude + currency. Idempotent — safe to run twice.

Run from the AIDA/ directory:
    python scripts/fix_listing_6a0b82_geocode.py --dry-run   # preview only
    python scripts/fix_listing_6a0b82_geocode.py             # apply

# The bug report identifies this listing as being in Cotonou, Benin.

# to Bangladesh in the currency manager — that's how this script's first
# run made things worse). For this one-off repair we override:
