Framing module doesn't overwrite existing framing module settings

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

In my library I have thousands of images, some with borders of one type for editing, another for instagram, others for print, and many without borders.

When I set up a style for export with the framing module set, it is additive to the current framing module rather than overwriting it. I understand why this is happening but I don't think it's useful. If I want to batch export images with a square border for instagram, or no border for printing for example, the style should be set to append and ignore any exisitng framing modules, rather than adding to them.

Alternatively being able to disable modules in the style setup would be another way of achieving this as I could then disable the existing framing module and add the new one to the base image.

I couldn't see another way to set the framing on a batch export so am open to suggestions.

Cheers

Steps to reproduce

1. Set up style module with only framing module with desired settings
2. use this style and export image

Expected behavior

use only appended framing, not add it to the existing framing setting on the original image

Start by reproducing the issue in darktable 5.6: apply a style containing only the framing module to an image that already has framing settings, then export it. Trace the framing module and style-export handling to determine how existing settings are combined. Done means the style's framing settings replace the existing framing for export, or the supported alternative is clearly implemented and tested.
