### 🐞 Description of the bug

PolygonData.move pethods works fine with PolygonData from poylgon but returns and empty one (no points) when we take Path.center_line.
Maybe the issue comes from the fact PolygonData is not closed.

### 📝 Steps to reproduce

``` python

from pyedb import Edb

edb_file = r"D:\Temp\real_board6.aedb"

edb = Edb(edbpath=edb_file, version="2026.1", grpc=True)
path = edb.layout.paths[0]
path.move(vector=[1.0e-3, 1.0e-3])

```

Reproduce the issue with the provided Windows Python example, then inspect Path.center_line and the PolygonData.move interaction, especially whether an open PolygonData is handled. Done means moving the path no longer produces PolygonData with no points, with a regression check for the reported case.
