New table backs /replay/info; composite PK (ViewerId, BattleId), index on
(ViewerId, CreateTime) for the newest-first list query. 50-row per-viewer
retention enforced by BattleHistoryWriter (next commit).

Lays the persistence foundation for the /friend/* API surface. Three new
model classes with composite PKs / unique constraints / FK cascades registered
on SVSimDbContext; 4/4 persistence tests pass on SQLite in-memory.

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.

Adds the bool column (defaults false) to the [Owned] ViewerClassData
entity and a two-test persistence suite that verifies round-trip and
default-value behaviour via SQLite/EnsureCreated.
Adds BGType persistence (0=Deck/1=CustomBG/2=RandomBG) to Viewer via two scalar
columns and an owned collection keyed (ViewerId, Slot). Two persistence tests
confirm round-trip and zero-defaults on fresh viewers.
