Migrate from JSON to PostgreSQL, update SLA to 99.5%
- Replace JSON file storage with PostgreSQL (pg package) - Add db.ts service for connection pool and schema init - Rewrite keys.ts, verification.ts, usage.ts for async PostgreSQL - Update all routes for async function signatures - Add migration script (scripts/migrate-to-postgres.mjs) - Update docker-compose.yml with DATABASE_* env vars - Change SLA from 99.9% to 99.5% in landing page
