Allow renaming of LoRA's Completed Runs

[hazratisulton]

By allowing users to rename their completed runs, they can quickly identify and distinguish between different runs.

• Give names to loras when training, "all files", "only python" - what I would like to see for me last two runs
• Rename existing loras
• When exporting, .zip needs to retain the same name

I like this idea, also it can ask for a name at a finetune start
