Three new EF entities for /campaign/regist_serial_code: SerialCodeEntry (code, message, window, enabled flag), SerialCodeRewardEntry (FK child, per-slot reward), and ViewerSerialCodeRedemption (composite-PK redemption record). Registered in SVSimDbContext with unique index on Code and cascade FK constraints. 3/3 persistence tests pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
