Updates an existing contract.<br/><br/>Fields an admin marked as required in Torii cannot be cleared: sending one empty fails with 400 and lists it in data.missingMandatoryFields. Fields you leave out are not checked.<br/><br/>Currency fields (e.g., amount) can be numbers ("amount": 1500, uses org default currency) or objects to set a different currency: "amount": { "value": 23000000, "currency": "EUR" }. Cannot set currency as a top-level field.<br/><br/>Optional lineItems are appended to the contract's existing line items (each needs a description; the same optional value fields as on create). Items cannot carry an id (400), existing items are never modified or removed here, and omitting lineItems leaves them unchanged. Removing a line item is done in the Torii web app. Read them back with GET /contracts/{idContract}?fields=lineItems.<br/><br/>
