This update adjusts the timing of changes to marital status for withholding tax calculations. Switching from an isolated status (single, divorced, widow) now takes effect at the start of the next calendar year, while becoming isolated (e.g., adding a spouse) is immediate. This aligns with Belgian tax regulations.

For withholding taxes:
-----------------------
Switching from an isolated status (single, divorced, widow) to a non isolated will take effect the start of the next calendar year.

But the other way around (becoming isolated) takes effect immediately.

This update simplifies our payroll structure for Belgium, aligning with new regulations regarding joint committees. It consolidates previous CP200 structures into a single 'Belgium' structure, ensuring compliance and streamlining payroll processing. Additionally, the update introduces key features for worker compensation, including unpaid time off, sick leave calculations, and adjusted ONSS base rates.

This update simplifies the approval process by replacing a complex 'approval_type' field with a straightforward boolean. The change clarifies required approvals and streamlines the flow for managers, making it easier to manage purchase requests. This enhancement improves efficiency and reduces potential confusion.

This commit aims to make some enhancement to the approval Category and Request Forms. Given that approval_type will either be 'purchase' or empty, it's better to replace it with a boolean field. The field "manager_approval" is now a Boolean with False being the old None and True being "Is required Approver", and the third option "Is Approver" is now dropped.
