BillsUnassign a vendor memo from a bill

Unassign a vendor memo from a bill

POST/partners/bills/{uuid}/unassign-vendor-memos

Removes a vendor credit memo previously applied to a bill.

Reverses an apply-vendor-memos application in full, restoring the bill open balance and the memo available balance. vendorMemoId is the vendor memo UUID. Vendor memos are not transactions, so POST /{uuid}/unassign-transaction cannot remove them. MCP equivalent: COUNT_unassign_vendor_memo_from_bill.
