[Feature Request]: Extras Tab and others as well Recursive Batch Process

### 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 ?

You give the folder that has other folders inside it, and then goes through all images in each folder inside and with the option to output folders of the same name as input or custom if possible with the same images but processed and folder structure kept.

### Proposed workflow

1. Go to extras tab
2. go to batch directory
3. check the tik/check box to turn on recursive
4. check the tik/check box to output the same folder name and structure (optional).
Process and done.

### Additional information

_No response_

Start at the Extras tab's batch-directory workflow and locate the existing image batch-processing entry point. Trace how input and output folders are selected; done means recursive processing can preserve the input folder structure or use matching custom output folders, with all nested images processed.
