Allow super admin or project creator to unlock task or revert to ready for mapping

Is your feature request related to a problem? Please describe.
In field mapping exercise there is maximum chances that user can lock task or mark task as mapped without mapping completely or leave the task mapping midway. In such cases, there is no workflow to undo these actions causing users not being able to map new features or provide false information to management team.

Describe the solution you'd like
Provide the access to super admin or project creator to unlock the tasks locked by mapper or reset the mapped task to ready for mapping state.

Describe alternatives you've considered
Alternatively, for now we can add map new feature button on mapper frontend irrespective of task but this will also cause problem in validation workflow later and its good that features and submissions are linked to task ID.

We have the code in place to already do this, in a PR that unlocks based on a cron.

The simple thing to do would be:

• Endpoint with project admin permissions
• Use the same logic as the cron for unlocking tasks (DRY code)

Actually, I realised this has a frontend part I think:

• Currently, if a user has locked a task, another user can't unlock it. This is a restriction imposed by the frontend.
• If the user if a project manager or greater, we want to allow them to unlock the task by calling the API.
• Related to Frontend user roles integration #2207, where we want to use const isProjectManager = useIsProjectManager();, the we we have conditional logic to allow the user to trigger an unlock of the task.
