3797569 - Argentina Withholding Taxes - Base Exemption Amount deducted twice on second payment / WTAK not updated correctly (RG 830)

When processing two vendor payments in the same calendar month for a supplier subject to Argentina Withholding Tax regime RG 830 (WT type GA), the system behaves incorrectly in one or more of the following ways:

1.  The second payment withholds a lower amount than expected — the Withholding Tax Base Exemption Amount appears to have been deducted twice (once against the cumulative base, once again against the individual payment).
2.  The WTAK accumulation table is not updated after payment postings (withholding amounts are present in WITH_ITEM but absent in WTAK).

**Example:**
- Payment 1: Net 110,000 | Exempt base 67,170 | Taxable = 42,830 | Rate 2% → WHT = 856.60
- Payment 2: Net 100,000 | Expected WHT = 2,000 | Actual WHT = 656.60 ← incorrect
