------------------

In the previous implementation, there was an issue where the duration of a task extension was not being recorded when a task was extended and then unlocked/stopped. Prior to the implementation of the task lock extension feature, the last recorded action for a task was always either "LOCKED_FOR_MAPPING" or "LOCKED_FOR_VALIDATION," which matched the task status. To update the duration, we used the current task status as the last action to filter the task history and update the last entry with the lock duration.

However, after the task extension feature was introduced, two additional last actions were possible: "EXTENDED_FOR_MAPPING" and "EXTENDED_FOR_VALIDATION." This introduced a discrepancy between the last recorded action and the task status. For example, the task status could still be "LOCKED_FOR_MAPPING" even when a user had extended the task. As a result, the entry with the action "EXTENDED_FOR_MAPPING" in the task history was not being updated with the correct duration.

To address this issue, this commit fixed the problem by retrieving the last task action and using it as the filter criteria for updating the task history, rather than relying on the task status as the last action.
