// Setting stores non-credential runtime configuration as key/value pairs.
// Groups: brand, rate, system, epay. Merchant credentials (pid + secret_key)
// live in the api_keys table; notification configs live in NotificationChannel.
// Default rows for the epay group are seeded on first startup (see
// model/dao/mdb_table_init.go seedDefaultSettings). All other groups start
// empty and fall back to hardcoded defaults until an admin sets them.
// Only exception: system.jwt_secret is auto-generated on first startup.
