Overwrite button disabled in paste conflict dialog

[geoffreysisco]

Describe the bug

In the paste conflict dialog, the Overwrite button is permanently disabled (grayed out) and cannot be selected.

This prevents the user from overwriting an existing file when pasting into a directory that already contains a file with the same name.

To Reproduce

1. Create a file (for example File1.mp3)
2. Copy the file
3. Paste it into the same directory where the original file still exists
4. The paste conflict dialog appears

Actual behavior

The dialog displays three actions:

Skip / Overwrite / Rename

However, Overwrite remains disabled and cannot be selected.

• Skip works normally
• Rename works normally
• Checking or unchecking "Do for all items" does not enable Overwrite
• The dialog cannot be dismissed except by choosing Skip or Rename

Expected behavior

Overwrite should be selectable so the user can replace the existing file.

Screenshots

Smartphone:

Device: Pixel 9 Pro (emulator)
OS: Android 16 / API 36
Rooted: No
Version: Debug build from latest release/4.0

Additional context

This appears related to the paste conflict dialog discussed in issue #4583, but the problem here is that the Overwrite action is never enabled, making it impossible to overwrite the existing file.
