NetworkTransform misses sync when GameObject is re-enabled; add option for automatic reassertion

Description
When using NetworkTransform in server-authoritative mode, if a NetworkObject is deactivated on clients (e.g. via SetActive(false) or scene streaming), any transform changes (e.g. via Teleport) made while it's inactive are not propagated to the client once it's re-enabled. This results in position mismatches, where the client sees the object at its old position while the server has already moved it.

There is no warning, and the desync is silent unless manually corrected.

Reproduction Steps
Spawn a server-authoritative NetworkObject with a NetworkTransform

Deactivate the object on all clients (via RPC or reparenting in a disabled object)

On the server, call Teleport(...) to move the object

Reactivate the object after a short delay

Observe: the client does not reflect the new position

Expected Behavior
Clients should receive the latest authoritative position of the object when it becomes active again.

Workarounds
Currently, we must:

Reapply Teleport() after reactivating the object, or

Use a coroutine to delay the teleport until the object is re-enabled, or

Use custom NetworkVariable logic or whatever boiler plate works instead of NetworkTransform

Suggested Fixes
Add a forceResyncOnEnable bool on NetworkTransform

Internally store the last known transform state, and resend it on reactivation

Or provide an OnNetworkObjectReenabled callback for developers to manually reassert state

从 NetworkObject 处于非活动状态时 NetworkTransform 对 Teleport 的服务器权威处理开始，然后重现所描述的禁用、移动和重新启用序列。确定如何在重新激活时重新应用最新的权威变换，并验证客户端无需第二次调用 Teleport 即可接收到更新后的位置。
