add Retrieve a Users Locked Tasks endpoint

[CollinBeczak]

Adds the new endpoint:
GET /user/:userId/lockedTasks?limit={Long}

This endpoint retrieves a list of data. For each task that is locked by a user, or where the user_id in the locked table matches the requested userId, it returns the task's id, challenge id, challenge name, and the time it was locked.

Example of output:

[

        "id": 50109,
        "parent": 63,
        "parentName": "Fix all roads in west Wichita",
        "startedAt": "2024-07-30T17:56:59.650-05:00"
