Implement Trash for recovering deleted content

[deshetti]

Needs a bit more thought into implementing the feature. We should wait on implementing this feature and decide on the priority based on user requests.

• How to manage access to the content.
  • My thought: Only admins should have access to the trash for recovering deleted content by default. Need to add another field in Policies for all content
• How to display trash content.
  • My thought: Provide an option for Trash in Settings -> Advanced to show all the content across entities where is_deleted = true. When recovering, is_deleted should be false and deleted_date should be null
• Delete the content permanently after the content is in trash for more than 30 days by default. This should be managed by an env variable.
  • Delete all the content where is_deleted = true and deleted_date date is more than 30 days.
  • Delete the Media files from S3 associated with the media in the trash
