Description

• Fix display column position being incorrect when using a DP as a table source https://github.com/Budibase/budibase/issues/13827 https://github.com/Budibase/budibase/issues/15011
• Increase width of create/edit column popover in data section to better display configuration for types like relationships Old (very cramped and cut off): New:
• Add loading spinner when uploading files. This also prevents attempting to upload additional files while an upload is in progress as I've disabled the dropzone while a file is uploading. https://github.com/Budibase/budibase/issues/14974
• Prevent adding multiple fields to single attachment cells and fields. You can now only select one file as intended. https://linear.app/budibase/issue/BUDI-8503/can-select-multiple-attachments-for-an-attachment-single-column

• The CreateEditColumn popover change is visible when editing an existing column but not when creating a new one. Could this be extended to the create flow as well?

It's the same component, and it definitely is there for creating a new column... What did you click to see the small one?

Creating: 360 width

Editing: 360 width

• When adding multiple attachments to the same single attachment field, I still see the same behaviour

How did you add multiple? You can't select more than one file in the file picker now (unless it's a multi attachment column of course), and you can't upload a new one until you delete the current file.
