Pull request overview

This PR implements new gRPC transport modes for PyMAPDL, adding support for Unix Domain Sockets (UDS), Windows Named Pipes (WNUA), and mutual TLS (mTLS) alongside the existing insecure transport. The implementation provides automatic transport selection based on platform and allows manual configuration through new parameters.

Key Changes:

• Added transport mode configuration with automatic platform-based selection (UDS on Linux, WNUA on Windows)
• Introduced new initialization parameters (transport_mode, uds_dir, uds_id, certs_dir) for transport configuration
• Integrated ansys.tools.common.cyberchannel for transport verification and channel creation
