gamer147 1813217c16 feat(friend): add ViewerFriend + ViewerFriendApply + ViewerPlayedTogether entities
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.
