"""Reconcile the PocketBase economy collections with the bot's user schema.

The expected field list is derived from core.economy._default_user() - the
single source of truth for what the bot persists - so this supersedes
add_stats_fields.py / add_quest_fields.py and also covers the fields those
scripts never added (fishing, prestige, quests, last_heist, ...).

PocketBase silently drops record fields that are missing from the collection
schema, so any drift here breaks features without a single error message.

Patches BOTH profile collections regardless of BOT_PROFILE. Only ever adds
fields; existing fields are never removed or retyped (type mismatches are
reported for manual review).

    python scripts/sync_pb_schema.py           # add whatever is missing
    python scripts/sync_pb_schema.py --check   # report only; exit 1 on drift
