Summary

This pull request refactors how query timeouts are set for statement handles in the mssql_python/cursor.py module. The main improvement is moving the logic for setting the query timeout from the execute method to the cursor initialization process, ensuring the timeout is consistently applied whenever the statement handle is allocated or reset.

Statement handle timeout management:

• Introduced a new _set_timeout method to set the query timeout attribute on the statement handle during cursor initialization, following best practices for performance. (mssql_python/cursor.py)
• Removed redundant timeout-setting logic from the execute method, centralizing timeout management in the cursor lifecycle. (mssql_python/cursor.py)
