-- Rename permit → subscription (master data only). The signed ledger keeps its
-- immutable `permitId` payload — NOT touched here. Data-preserving ALTER RENAMEs
-- (SQLite 3.25+) rather than drop/recreate, so existing subscriptions survive.
-- Adds per-subscription pricing (price_minor + period + currency) and a site-wide
-- default monthly price. See wiki/entities/subscription.md.
