- Add getEmployeeNavItems() to app-sidebar.tsx for users with type='employee'
showing Dashboard, My Leaves, Overtime Requests, My Attendance, My Payslips
- Route employee users to their own nav instead of admin getCompanyNavItems()
- Move GET index routes for leave-applications, attendance-records, overtime,
and payslips outside permission:manage-* middleware so employees can access
their own records without admin permissions (controllers already scope by user)
