Retrieve a Quote for a PCB with a Specific Version.

Retrieves a quote for a PCB with a specific version at the given quantity and service tier,
returning total and unit prices, component and labor costs, lead time, and the manufacturing
specifications that were quoted.

The quote uses the specifications stored on the PCB version. To quote different
specifications (layer count, colors, copper weight, and so on), update them first with
PUT /api/v2/pcb/{pcb_id}/{pcb_version}/version.

Components are quoted from each BOM line's approved vendor list. Check valid before relying
on the prices: when it is false, invalid_reasons explains why the PCB could not be fully
quoted. GET /api/v5/pcb/{pcb_id}/{pcb_version}/ready/{quantity} reports the same problems in
more detail, and whether the PCB can be ordered.
