[3 Feature Requests]: Add "open in explorer" to the workflow saved / Also allow for custom folder saving of workflows // save ALL workflows that did not finish their generation

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

At first I was confused whenever I pressed save or save as, I was going to revent to the old UI just to be able to choose where to save my workflows.
Then I realized they were inside "User" folder inside comfy.

The failed workflows is important for people who spend lot of time building their workflows and then never able to create one single image and they end of losing their WF because they forgot to save it.
What to do : ANY QUEUE pressing => saves the current workflow even if no image is produced, this helps saving work

### Proposed workflow

1)
1. Menu
2. Workflow
3. Open workflows directory

2)
1. Menu
2. Workflow
3. Modify workflow path

3)
1. Press gen
2. Workflows fails
3. it is saved in a failed workflows history
4. If the gen succeeds, it is deleted (optional)
