Bug 1: SeatSkuService.php:381 - regex has syntax error
'/^([A-Za-z]+)(\d+)排(\d+)座$/' → '/^([A-Za-z]+)(\d+)排(\d)座$/'
The third capture group only needs single digit (col number 1-9).
Bug 2: ticket_detail.html:416 - frontend accesses specBaseIdMap as object
but PHP returns flat integer: specBaseIdMap['A_1'] = 2001 (int), not {spec_base_id: 2001}.

- renderSeatMap(): add data-row-label + data-col-num attrs for specBaseIdMap key format
- toggleSeat(): change seatKey from "0_0" (numeric) to "A_1" (label_colNum) to match specBaseIdMap
- removeSeat(): use [data-row-label][data-col-num] selector
- submit(): refactor from 1 goods_params (zone-level) to N entries (seat-level, stock=1)
- Plan B fallback: if specBaseIdMap[key] missing, use sessionSpecId

P0-1: issueTicket() now checks for existing tickets by (order_id, spec_base_id)
before inserting. Prevents duplicate tickets on HTTP retry/multi-instance.
P0-3: Removed |raw from simple_desc and content in ticket_detail.html.
Prevents stored XSS via malicious admin content injection.
P0-4: getQrSecret() now throws exception if VR_TICKET_QR_SECRET is unset,
instead of falling back to insecure default key.
