Squash the pre-production migration history into fresh core, fedwiki,
and stripe baselines and reduce the canonical source list to those
three streams.
Update sqlc configs, generated queries, raw SQL, tests, and docs while
keeping provider tables schema-qualified.
BREAKING: existing local database volumes must be wiped because goose
version history restarts from the new baselines.
Update subscription model and SQL to include commitment fields. Add
SubscriptionScheduledChange types and queries, implement
UpdateSubscriptionItemPriceProduct, and adjust reconciliation and tests
to update core item rows when a Stripe item retains its ID but its
price/product/quantity changes.
