refactor(types): align entity types with backend API responses

Adjust all entity types to match actual backend response shapes.
String-typed numeric fields (Shop.rating, Shop.commissionValue,
WalletTransaction.amount) now correctly typed as strings.
Post.linkedOrderId changed from SnowflakeId to number (backend int64).
Removed fields absent from backend: Order consumer/player/shopName,
Review fromUserAvatar/toUserId, Dispute initiatorId/initiatorName,
Post authorRole/quotedPostId, Comment postId, ChatSession
readonly/lastMessageAt, ChatMessage senderName/senderAvatar.
Added Player.gender field.
