fix(ui): 侧栏「资金内控」图标缺失——MainLayout 补 Lock 到 import 与 iconMap

任总 2026-10-14 10:49 报「资金内控：导航栏缺少图标」。
根因：permission.ts:40 icon:"Lock"，而 layouts/MainLayout.vue 的
@element-plus/icons-vue import 与 iconMap 均无 Lock ⇒ iconMap["Lock"]=undefined
⇒ <component :is="undefined"> 渲染为空。全量核：菜单 40 项 / 19 个不同 icon 值，
仅 Lock 真缺。本提交仅该 1 文件 2 行（import + iconMap 各补 Lock），
不改其它图标、菜单顺序、分组、角色可见性。
