feat(Phase2): 修复 seatSpecMap 生成 + room ID 硬编码问题

关键修复:
1. BatchGenerate(): 新增 extends.seat_key 字段写入 GoodsSpecBase
2. BatchGenerate(): 新增 type 字段写入 GoodsSpecValue（4维spec类型）
3. ticket_detail.html: renderSeatMap() 不再用 room_001_ 硬编码，改用模板实际 roomId
4. Goods.php: seatSpecMap 注入（已在上次提交）

数据库修复:
- 为 vrt_goods_spec_value 新增 type 字段
- 重新生成商品 118 的规格数据（含 seat_key 和 type）
