feat: 装配线看板修正、统一密钥Hardman_2026、操作日志追溯、日志按天存储

Dashboard 移除 CNC/清洗机等不存在设备，改为纯装配线看板（扫码枪+拧紧枪+人工）；JWT/内部token统一为 Hardman_2026 写入各 etc/*.yaml，MES 建表 DSN 改读 yaml；event_log 增加 workOrderNo/operator，BOM/备料/PLC下发/拧紧/扫码报工/半成品/AGV 全链路埋点，日志页支持工单号/操作人筛选；MES/WMS 日志按天存储（dailyWriter），WMS SetWriter 用 logx.NewWriter 适配
