[FIX] hr_timesheet: AccessError editing timesheets
[FIX] hr_timesheet: AccessError editing timesheets

Make department_id of account_analytic_line readonly, so that when the field is written it is not also propagated to the employee, which
may fail when the user has write access to timesheets but not to employees.

Fixes #14084
