- Backend: add GET /usr/users/{id} detail endpoint that returns the user row plus its permissionCategoryIds
- Backend: add GET /usr/permission-categories listing for the permission grid (active categories only)
- Frontend: UserDetail consumes both endpoints to populate edit form and the permission grid

V2 ALTERs all 6 b* columns across tUser/tStaff/tPermissionCategory/
tModule from TINYINT(1) to BIT(1). MySQL preserves data on the type
change (0 → b'0', 1 → b'1') and indexes survive the modify.

MyBatis-Plus entity Boolean fields and existing 'WHERE bDeleted = 0'
queries continue to work — MySQL Connector/J 8.x maps BIT(1) ↔ Boolean
automatically and accepts integer literals via implicit conversion.

Verified: setup-test-db + mvn test → 149/149 pass with V2 applied.

Also updates docs/03-数据库设计文档.md (schema SSoT) so the table
descriptors say bit(1) instead of tinyint(1).

部门 (sDepartment) lives on tStaff, not tUser. Showing/editing it on
the user form was misleading — it implied the value would be saved
against the user, but the backend has no such column on tUser. The
user list still surfaces 部门 via the LEFT JOIN on tStaff, which
remains correct for display.

Removes:
- 部门 form field on UserDetail
- DEPARTMENTS constant (now unused)

- Remove the green '已绑定' badge from StaffPicker; the prototype
  doesn't show one and it's confusing in create mode (nothing has
  been saved yet).
- On staff selection, auto-fill 用户号 (sUserNo) and 用户名 (sUserName)
  with the staff's Chinese name to match prototype behavior; user
  can still override either field after selection.

Backend:
- StaffSearchVO (iIncrement / sStaffNo / sStaffName / sDepartment)
- StaffMapper.searchActive(keyword, limit) — LIKE on name + staff no
- StaffController GET /api/usr/staffs?keyword=&limit=
- UserListVO + UserMapper.xml: expose iStaffId so edit mode preserves
  the binding when user doesn't change 员工名

Frontend:
- api/staff.ts → searchStaff()
- StaffPicker.tsx: input + dropdown with debounced search, '已绑定'
  badge when an iStaffId is bound, click outside to close, search icon
- UserDetail: replace 员工名 PrimInput with StaffPicker; track iStaffId
  in form state; send to backend on save (no longer omitted)

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.

Reverses the earlier 'hide unsupported fields' decision per user request
to strictly follow the prototype look. Brings back:

- Full dark sub-toolbar: 新增 / 修改 / 删除 / 保存 / 取消 (separator)
  功能 / 作废 / 重置密码 / 取消作废, with status chip + settings gear
  on the right and 已选权限 counter
- 9-field 3x3 form with prototype's required-field cyan tint, 制单人
  showing 保存后自动生成 placeholder in new mode
- 6 perm tabs (权限组 / 客户 / 供应商 / 人员 / 工序 / 司机)
- 30-row permission grid with hover, accent-soft selected row, filter
- Scope tabs with master enable + 4-col grid of items
- Floating vertical 帮助 button on right edge

Permissions and the no-op buttons are visual-only — they don't round-trip
to backend. Save still sends only sUserNo/sUserName/sUserType/sLanguage/
bCanModifyDocs (iStaffId and permissionCategoryIds intentionally omitted).

Adds bespoke Primitives.tsx (Field/PrimInput/PrimSelect/PrimCheckbox/
ToolbarBtnDark/ToolbarBtnLight) so this screen renders pixel-faithful
to prototype rather than picking up AntD chrome.

- Sidebar 系统管理 now contains only 角色管理 / 菜单配置 / 操作日志
  (用户列表 and 系统模块配置 are accessed via mega-nav, not duplicated
  in the tree).
- MegaNav rebuilt as full-viewport dark layout per prototype: dark
  topbar with highlighted 全部导航 chip, 150px left rail of categories
  (active = accent + white left border), right grid of category columns
  with bordered titles and muted/featured items.
- MEGA_COLUMNS expanded to 8 columns matching prototype 系统设置
  (期初设置 / 用户管理 / 系统参数 / 计算方案 / 日志 / 开发平台 /
  API对接管理 / 系统模块).

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.

Per docs/04 production stack: Vite + React 18 + TypeScript + AntD 5 +
Redux Toolkit + React Router v6 + Axios. Theme tokens copied from
prototype/XLY-ERP.html so density, colors, and layout match. Pages:
Login, Home, UserList, UserDetail, ModuleConfig — wired to existing
endpoints (/api/usr/auth/login, /api/usr/users, /api/mod/modules).
Backend-unsupported fields (user permission grid, 18 module fields,
iStaffId picker) hidden per scope. Sidebar/MegaNav remain static
reference data; dashboard stats hardcoded (no endpoint).

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.
