TeleportGUI

Added / 新增

• Added automatic save-data migration from the mod's predecessor, GeyserTPC. If the new storage is empty and <world directory>/GeyserTPC/storage.json exists, warps, homes, and default homes are imported automatically. The old file is only read, never deleted, and can be cleaned up manually after verification.
  支持从模组前身 GeyserTPC 自动迁移存档：当新存档为空且 <世界目录>/GeyserTPC/storage.json 存在时，会自动导入其中的传送点、家园与默认家园。旧文件只读不删，确认无误后可自行清理。

Fixed / 修复

• Fixed TPA requests being consumed prematurely when the destination was unsafe and the player was waiting to confirm a forced teleport. Requests now remain valid until teleportation actually completes and are preserved if the player cancels.
  修复 TPA 请求在「目标位置不安全、等待玩家确认强制传送」时被提前消耗的问题。现在请求会保留到传送真正完成，玩家取消后请求仍然有效。
