"""Add `latitude` / `longitude` to the SITES collection.

Needed by the rain outlook card on the Overview page — Open-Meteo is
queried per site coordinate. Sites without coordinates are listed as
"no location set"; nothing else in the app reads these fields.

Idempotent: fields already present are left alone. Existing fields and
data are preserved — this PATCHes the collection's field list rather
than replacing it. Run `pb-backup-collection.py SITES` first if you want
a schema snapshot to fall back on.

Credentials come from .env.local (or the environment):
