council(execute): FrontendDev - Issue #9 P1 submit() refactor (seat-level goods_params)

- 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

+### P1 实现记录
+
+**已完成的改动**（`ticket_detail.html`）：
+
+1. **`renderSeatMap()`**：为每个座位 div 新增 `data-row-label` 和 `data-col-num` 属性，用于生成与 `specBaseIdMap` key 格式一致的 seatKey
+2. **`toggleSeat()`**：将 seatKey 从 `rowIndex_colIndex`（如 `"0_0"`）改为 `rowLabel_colNum`（如 `"A_1"`），匹配 `specBaseIdMap` key 格式
+3. **`removeSeat()`**：改用 `[data-row-label][data-col-num]` 选择器查找座位元素
+4. **`submit()`**：从 Zone 级别提交（1 行 goods_params）改为座位级提交（N 行 goods_params，每座 stock=1，spec_base_id 从 `specBaseIdMap[seat.seatKey]` 获取）；降级兜底：若 specBaseIdMap 无对应 key，使用 sessionSpecId
+
+**seatKey 格式约定**：
+- 格式：`{rowLabel}_{colNum}`，例如 `"A_1"`, `"B_5"`
+- 与 BackendArchitect `SeatSkuService::BatchGenerate()` 返回的 `spec_base_id_map` key 格式保持一致
