Resolve Permission Conflict during Project Deletion.

-----------------------------------
The current setup for deleting a project involves conflicting permission checks. In the resource class function, users with a Project Manager (PM) role are allowed to delete projects. However, in the service function responsible for project deletion, the check only permits organization managers or system administrators to perform this action.

To address this inconsistency in permission checks, this commit streamlines the process. It eliminates the permission check within the service function, thereby enabling users with PM roles within a project to successfully initiate project deletions.
