Discrepency in the fetched table properties

### Apache Iceberg version

None

### Please describe the bug 🐞

I am using Apache Polaris as catalog and when i load the table using pyiceberg, the response has config that is different from what i get when i use Polaris CLI and not only that when i use the file system from this table, i am getting `Permission Denied` errors, suggesting the credentials in the table are wrong.

Details:

```
polaris --profile root tables get --catalog "senec_catalog" --namespace "Senec.Stage.Bronze.Ampace_V3LFP" "BmsAmpaceV3ModuleMeasurement"
```
returns a table with the config property as follows:
```
, "config": {"s3.path-style-access": "true", "s3.endpoint": "http://localhost:9008"}
```

however, the rest api cal inside `catalog.load_table(table_identifier)` has a response that contains the config that looks like this:
```
{'s3.path-style-access': 'true', 's3.access-key-id': 'NFAIYHBUDHR1VBDHR8G0', 's3.secret-access
-key': 'L4Q_0W4We1ClcHsg8t0A5RcazPu4Xx1TR9P5-fbn', 's3.session-token': '***', 'client.refresh-credentials-endpoint': 'v1/senec_catalog/namespaces/Senec%1FStage%1FBronze%1FAmpace_V3LFP/tables/BmsAmpaceV3ModuleMeasurement/credentials', '
expiration-time': '1776355429000', 's3.endpoint': 'http://localhost:9008', 's3.session-token-e
xpires-at-ms': '1776355429000'}
```
which would have been okay but using a filesystem created using the io from this table is always resulting in permission errors, so i have to manually set the table properties like so:

```
self.tbl.io.properties["s3.endpoint"] = self.catalog.properties["s3.endpoint"]
self.tbl.io.properties["s3.endpoint"] = self.catalog.properties.get("s3.endpoint")
self.tbl.io.properties["s3.access-key-id"] = self.catalog.properties.get("s3.access-key-id")
self.tbl.io.properties["s3.secret-access-key"] = self.catalog.properties.get("s3.secret-access-key")
self.tbl.io.properties.pop("s3.session-token", None)
```

Could anyone tell me why is this the case? This is related to #1958 as i am trying to use the filesystem to delete the orphan files.
