Add use_fabric_endpoint parameter to MicrosoftAzure class (#1357)

This change adds support for the use_fabric_endpoint parameter to the
MicrosoftAzure object store class, enabling connections to Microsoft
Fabric OneLake storage.

The parameter allows users to specify that they want to use Data Lake
Storage Gen2 endpoints (dfs.fabric.microsoft.com) instead of the default
Azure Blob Storage endpoints (blob.core.windows.net), which is required
for OneLake/Fabric storage access.

Implementation follows the same pattern as existing boolean parameters
(use_emulator, allow_http) by:
- Adding the parameter to the PyO3 signature macro
- Adding it as Option<bool> to the function parameters
- Conditionally calling with_use_fabric_endpoint() on the builder

Fixes #1356
