ModalRemoveDoc focus and keyboard accessibility

[Ovgodd]

Bug Report

Problematic behavior
The "Remove Document" modal could not be opened via keyboard, and had no focus trap:

• Users pressing Enter had no effect
• Focus would escape the modal content

Expected behavior/code

• Pressing Enter on the appropriate trigger opens the modal
• Focus is trapped inside the modal
• ESC or cancel properly closes it

Steps to Reproduce

1. Navigate to the remove button using Tab
2. Press Enter — nothing happens
3. If opened manually, try tabbing — focus escapes modal

Possible Solution

• Add a focus trap inside the modal
• Add keyboard handler with Enter/Space support
