Thai Localization - Government Expense

This module connects purchase requests with expense reports for Thai government workflows. On an expense report, a user can select an approved purchase request belonging to the same employee; the purchase request lines are then shown in a new "Expense from PR" tab. Saving the report automatically creates the corresponding expense lines in the "Expense" tab, and the temporary purchase request lines are cleared afterwards.

Business rules added: - When submitting an expense report, the total untaxed amount of the expenses cannot exceed the estimated amount of the linked purchase request, unless the HR manager ticks "Skip Amount Check". - When approving an expense report, the linked purchase request must already be in the "Approved" status. - A purchase request that is linked to a non-cancelled expense report cannot be reset to draft or rejected; the expense must be cancelled first.

For advances, the report shows a "Returned Date" and a clearing term (30 days after receiving the money or 30 days after returning to the office), and the clearing due date is computed automatically. The clearing term setting is hidden in the reminder configuration because Thai government rules already fix 30 days.

Purchase request and journal entry forms gain an "Expenses" button showing how many expense reports are linked, and expense searches can be grouped by purchase type.
