Retrieve and approve Remote.com employee timesheets via the Timesheet API

Steps

1. Confirm the target employment has an active timesheet before querying - timesheets must already be created for the employment
2. Call List Timesheets, optionally filtering by status (open, submitted, in_calibration, processed)
3. Call Show Timesheet by ID to read the full breakdown, including regular_hours, overtime_hours, night_hours, weekend_hours, holiday_hours, and on_call_hours, each as {hours, minutes}
4. Inspect the time_tracking array for per-shift entries, each with a type (regular_hours, overtime, on_call, break, time_off, public_holiday) and a day/night time_breakdown
5. Call the Approve Timesheet endpoint when approval_required is true and the timesheet is ready, or Send Back with a reason to return it for revision
