Updates an existing VAT rate with a new percentage and/or effective date.

**What can be updated:**
- VAT percentage (0-100)
- Effective date (dateFrom)

**Validation rules:**
- VAT percentage must be between 0 and 100
- dateFrom must be a valid date
- The system validates that the updated dateFrom does not overlap with other VAT rates
- If the VAT rate does not exist, a NotFoundException is returned
- If validation fails, you will receive an error message explaining the issue

**Important notes:**
- Changes to the effective date affect which invoices/quotes use this rate
- Documents already issued keep their original tax rate
- The system automatically recalculates which rate applies based on the updated dateFrom

**Note:** This endpoint requires the WsSettings.manageSettings permission.
