Tracking Category "View Own Only" – Restrict PM Visibility to Users in assigned category

When a Project Manager is assigned to a specific Tracking Category and their permissions are set to "View Own Only" for that category, their visibility in the Time & Expense Explorer and Individual Time Explorer should be automatically scoped to only display staff who fall under that same Tracking Category.

Current Behaviour : Project Managers with "View Own Only" permissions on a Tracking Category can still see time and expense entries for all staff, regardless of whether those staff members belong to their assigned Tracking Category.

Desired Behaviour : When a PM is:

1. Assigned to a specific Tracking Category, and

2. Set to "View Own Only" for that Tracking Category

Then, in the Time & Expense Explorer and Individual Time Explorer, they should only see staff members who belong to that same Tracking Category - not all staff across the organisation.

Business Use Case : Regional Project Managers should only have visibility into the time and expenses of staff within their own region (Tracking Category). This ensures proper data segregation, and prevents Project Managers from accessing data outside their scope.
