Add "Don't Ask Again" Option in Delete Files Modal

Description:

Currently, every file deletion requires confirmation, which can be repetitive and frustrating for users who frequently delete files.
Enhance the delete confirmation modal by adding a "Don't ask again" checkbox. adding this feature will be beneficial for:

• moderators improving their workflow efficiency,
• Gives users control over their experience by allowing them to disable repeated prompts.

It should also contain Reset Option: Allow users to re-enable the confirmation from settings.

Steps to reproduce:

1. Go to any channel
2. In files aggregator
3. option -> delete any file -> check the prompt.

Expected behavior:

I expect Delete modal should show the option (checkbox) where user can choose to prompt Delete File again or not.

Actual behavior:

There is not any option.
