Take an article in for repair

Opens a repair order in the intake state — the article is now in the store’s custody. article.label is the only required article field; add skuId and serial when the unit is identifiable and purchasedAt when the original sale date is known. purchasedAt is RECORDED ONLY — the server derives nothing from it and never adjusts a price; the warranty helper that reads it lives in the till UI, and quoteAmountCents is entirely caller-supplied either way. MONEY: quoteAmountCents is the price quoted to the customer and depositAmountCents the acompte ALREADY captured at the counter (typically 30%; send 0 if none was taken). This endpoint captures nothing itself — take the acompte first, then record it here. There is NO update route: once open, neither the quote nor the acompte can ever be revised, so do not open an order on a provisional estimate. id is CALLER-SUPPLIED and is the dedup key: on a timeout retry with the SAME id — a 409 CONFLICT then means your first attempt committed, so read it back with getRepairOrder rather than minting a new id. 422 when depositAmountCents exceeds quoteAmountCents, or when expectedPickupDate is not in the future. Note article.serial is stored EXACTLY as sent — unlike the sale and warranty paths it is neither upper-cased/trimmed nor IMEI-checksummed here, so send an already-canonical value if you want it to match a serial captured elsewhere.
