feat(sync): 跨实例同步第1轮——同步功能表、InstanceSyncedOptions 类型与实例元数据字段

- 新增 4 个 migration：同步功能表/instance_servers 扩展/synced_pack_selection/禁用发现选项

- 新增 InstanceSyncedOptions 类型（per-instance 同步开关）

- InstanceMetadata 增加 synced_options 字段并在 3 个查询点填充

- instance_rows 新增 get_instance_synced_options

- 前端 GameInstance 增加 synced_options 类型
