feat: 账套模式全量接入 — 12个API entity_id统一走token解析链 + 前端登录选公司/切换器重签token

- 后端: kpis/bsc_layers/cash/predict/growth_quality/tax_compliance/data 的 entity_id 参数统一改为 Depends(get_entity_id)
- 前端: 拦截器删除自动附加X-Entity-Id/entity_id; 登录页公司选择器(按用户名授权过滤); 切换器改POST /auth/switch-entity重新签发token+整页刷新; ReportCenter同步改造
- 修复前后端不匹配: login-entities路由→/auth/entities; login响应entity_id取user.entity_id
