Support wandb logging in Swift Megatron SFT

[firefighter-eric]

Describe the feature
Please describe the feature requested here(请在这里描述需求)

Currently, when using Swift Megatron for SFT (Supervised Fine-Tuning), parameters like:

wandb_exp_name ..................................
wandb_project ...................................
wandb_save_dir ..................................

are shown in the CLI, but they are not actually passed through to Megatron's SFT training pipeline. As a result, wandb is not initialized, and no metrics are logged to the Weights & Biases dashboard.

Please add arguments like project name, run name like transformers arguments
