Refactor GPU passthrough and device config handling

Switches device configuration to use pct set format for GPU passthrough, simplifying config and improving GUI visibility. Updates GID handling logic for devices, streamlines fix_gpu_gids function, and improves container creation logging and API reporting. Removes commented-out MOTD/SSH debug setup from build copy.func.
