Copy a QR design. The copy is named Copy of <name> (with (1), (2) and so on added when that name is already used at the location) and counts towards the location's plan allowance for QR codes, like a new design (402 when the plan doesn't include QR codes or the allowance is used up). Returns the new design.

Prerequisites: a bearer token for the account, and the design's id (id in GET /api/v1/qr-codes/template/list).

Authentication: Account token. The design must have been created under your token's account; otherwise 404.

Rate limit: none.
