Sale Timesheet Order Line Sync

This module keeps timesheets consistent with the task they belong to. When a user changes the sale order line on a task and saves it, Odoo automatically updates the sale order line on the timesheet entries of that task that have not been invoiced yet.

Where it applies: - It works on tasks that use the fixed price billing type (pricing_type = fixed_rate). - It only touches timesheet lines that are still not linked to an invoice (timesheet_invoice_id is empty). - Lines that already have a different sale order line are updated to the new one.

What it does not do: - It does not change timesheets that are already invoiced. - It does not run when the task is saved without changing the sale order line. - It does not add new menus, buttons, reports or scheduled jobs.

Business effect: after correcting the sale order line on a task, the not-yet-invoiced time entries follow the same sale order line, so future invoices are generated against the right order line without manually editing each timesheet line. The change is applied with elevated permissions, so users who can edit the task do not need extra rights on the timesheet records.
