Extend API Functionality: Add Approval Status Filtering and Task Information for Timesheet Entries

Currently, the https://app.peopleforce.io/api/public/v2/time/timesheet_entries endpoint allows you to get a list of timesheet entries, but it lacks certain features necessary for more efficient data management. Namely.
1. Filtering by approval status: The current API does not support filtering timesheet records by approval status. It is necessary to add the ability to filter records by adding a new state parameter to the request.
2. Getting information about tasks: When creating a timesheet, the user selects a task related to the project. It is important to include this task information in the API response.
Goal: Extend the API functionality to:
- Support filtering of timesheet entries by approval status.
- Include the task information associated with each time sheet entry in the API response.
This will allow developers to receive only approved records and see specific tasks associated with these records
