Tier codes are not unique across platforms (e.g., "essential" exists for
OMS, marketplace, and loyalty). Using tier_code caused feature limits to
be saved to the wrong tier. Switched to tier_id (unique PK) in routes,
service, and frontend JS. Added comprehensive unit and integration tests
including cross-platform isolation regression tests.
