feat(backend): 出入库定价字段消歧 + 总利润落库 + 成本仅管理员可见

Browse Source 
- 字段重命名（旧列弃用保留，启动幂等回填 BackfillPricingColumns）：
  入库 unit_price/total_price/total_amount → cost_price/cost_amount/cost_total；
  出库同前缀 + 新增 sale_amount（售价小计）/ sale_total（应收）/ profit_total（总利润）
- 建单落三值；确认售价联动重算 sale_amount/sale_total/profit_total；
  确认进价回填成本后联动重算受影响出库单利润（recalcStockOutProfit）
- 出库 List/Get 对 operator/readonly 抹零成本与利润（stripStockOutCost 服务端兜底）
- 兼容一版：Create/Update 接受旧 key unit_price 回落（v1.0.87 及之前客户端）
- SUM 聚合/价格趋势/导入/种子工具同步切新列；测试全量改名 + 6 个新回归
