List the approved and ready tasks of a given workflow request in multi step approval processes

[sadilchamishka]

Purpose

For multi step approval tasks, when the first step is approved, and the second step has to be approved by the same user (Ideally shouldn't happen), as the same workflow request is corresponds to both approval tasks, only one (first approved task) will be shown where the next ready approval task is not filtered when filter without status.
If filter by ready state, the ready state approval task will be shown.

The above mentioned case is fixed by this PR.

Pull Request Overview

This PR fixes an issue in multi-step approval processes where only the first approved task was shown when the same user needs to approve multiple steps of the same workflow request. The fix ensures that subsequent tasks in READY or RESERVED states are also displayed alongside approved tasks.

• Added APPROVED status to the TaskStatus enum with proper documentation
• Modified the duplicate filtering logic to preserve subsequent approval tasks for the same workflow request
• Renamed variable for better clarity and added logic to handle APPROVED status differently
