Main changes explained:

• Update taskController.js to check seeNumberOfTimesTimeAdded / viewTaskExtensionCount permission before returning deadlineCount in getTasks, getTaskById, and getTasksForTeamsByUser
• Add canSeeTaskExtensionCount helper that checks the permission via hasPermission
• Add removeTaskExtensionCounts helper that strips deadlineCount from task results when permission is absent
• Update taskController.spec.js to cover the case where deadlineCount is hidden when permission is missing

How to test:

1. Check into current backend branch
2. Run npm start
3. Clear site data/cache
4. Log in as Admin
5. Go to Dashboard → Tasks tab
6. Verify deadlineCount is visible for Admin/Owner by default
7. Go to Permissions Management and remove seeNumberOfTimesTimeAdded from a user

Suggested change

	(await hasPermission(requestor, 'seeNumberOfTimesTimeAdded')) ||
	(await hasPermission(requestor, 'viewTaskExtensionCount'));
	(await hasPermission(requestor, 'seeNumberOfTimesTimeAdded'));

Is viewTaskExtensionCount implemented as something else or a different name for what ended up as seeNumberOfTimesTimeAdded? I don't see it used anywhere.
