[FIX] hr_holidays: correct domain to compute timeoff and allocation request

Steps to reproduce:
- open kanban view of department from employee module.
- click on 'Allocation Requests' and 'Time Off Requests'.

Issue:
- When viewing the department's allocation and time-off requests in the employee
  module, all department data is displayed, regardless of the department
  selection.

Solution:
- The issue is resolved by correcting the domain, ensuring that only data
  related to the selected department is displayed. This adjustment results in
  accurate department-specific request information.
