Idempotent (INSERT IGNORE on unique keys) script that populates:
- tStaff: 20 print-industry employees with realistic Chinese names,
  staff numbers (S0001..S0020), and varied departments
- tUser: admin + 18 business users, all BCrypt(666666), linked to
  staff rows; mix of 超级管理员 / 普通用户, languages zh/en/zh-TW,
  with one bDeleted=1 to demo the 作废 column
- tPermissionCategory: 30 groups matching prototype's permission grid
- tUserPermission: department-correlated permission grants
  (e.g. 财务部 users get PERM_FINANCE + PERM_VIEW_ORDER_PRICE)
- tModule: 5 KPI flow trees (估价/订单/拼版/送货/采购) + 系统设置,
  ~30 nodes with proper parent/child relationships

Final SELECT prints row counts for verification.

Previously the script used hardcoded defaults (127.0.0.1:3306 / xly_erp)
and ignored the user's remote test DB. Now sources .env.local like
setup-test-db.sh does. Documents the prereq that Spring Boot must have
started at least once (Flyway applies V1) before seeding.

Enables the new frontend/ Vite app (localhost:5173) to call the backend
across origins. Adds OPTIONS preflight permitAll. Seed script provisions
an admin user (sUserName=admin / password=666666) for first-run login.

- setup-test-db.sh: prepend Homebrew mysql-client bin paths if present
- test.sh: skip frontend build/lint/test segments when frontend/ absent
