The Belgian payroll departure notice wizard now decides when to show the notice respect field based on the calculated notice period instead of fixed reason codes. This makes the form behavior more accurate and easier to maintain when departure situations vary.

In belgian l10n payroll the departure notice wizard currently hides the
notice_respect field using the hard-coded departure_reason_codes. This
commit uses the computed value of weeks/months of notice to hide/show
the field.
