This pull request enhances the data post functionality by adding support for multi-user editing, preventing data loss and improving collaboration. It also refactors access control logic and updates components to reflect the new permissioning system.

Highlights

• Multi-User Editing Support: This PR introduces support for multi-user editing of data posts, preventing users from overwriting each other's changes. It adds a modal to warn users if a draft has been edited by someone else while they were working on it.
• Component Updates: The PR updates the PostCard component to use canManagePost instead of isAdmin to determine if a user can manage a post. It also modifies the PostFormSchema to include id and updatedAt fields.
• Access Control: The PR refactors access control logic using getCanManagePost and getCanViewPost functions to determine user permissions for managing and viewing posts.

Code Review

This pull request introduces a valuable feature for handling multi-user editing of data posts by detecting concurrent edits. The implementation includes a new modal to warn users about potential overwrites, which is a solid approach. Additionally, the refactoring from isAdmin to the more descriptive canManagePost and canViewPost greatly improves the clarity and maintainability of the access control logic. The changes are well-structured and consistently applied. I have identified one critical issue with the date comparison logic used for conflict detection that needs to be addressed.

Also I have noticed that the draft badge is kinda hanging out in the middle of nowhere instead of being close to the action dropdown button
