The requested URL was not found on the server (local server)

从 mergin/server/src/storages/disk.py 中的 move_to_tmp 开始，然后检查 mergin/server/src/controllers/project_controller.py 中 push_finish 附近的代码。复现本地项目的 push，并沿着 traceback 跟踪 os.renames。完成标准是 push-finish 请求不再引发报告中的跨设备链接错误，并返回预期的响应。

During pushing new changes on the project, there is an error, when using server on localhost. So it have probably something with virtual environment.

Error: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
