refactor(store): adapt Zustand stores to backend-aligned types

- orders: remove name fields from creation, keep dispatchMode logic
- chat: remove readonly/senderName/senderAvatar references
- reviews: remove fromUserAvatar/toUserId, simplify participant check
- disputes: remove initiatorId/initiatorName from creation
- posts: remove authorRole/quotedPostId, keep linkedOrderId as number
- comments: remove postId from creation
- wallet: use string amounts
