- admin controller: add updatedAt to interview/resume selects; add orderCount,
  todayOrders, totalRevenue to overview
- admin.vue: enrich all tabs with more fields
  - overview: order cards (count, revenue)
  - users: wxOpenid, email, createdAt, interviewCount, vipExpireAt, role badge
  - interviews: user email, updatedAt, summary preview
  - orders: title, type, channel, paidAt, wxTransactionId, refund info
  - resumes: user email, updatedAt
  - share: sharer phone, shareCode, isActive, visitorId(IP), creditedAt
  - admins: email, createdAt
- user.schema: add unique indexes on phone/wxOpenid/email; pre-save hook
  requiring at least one contact method
- user/about: add WeChat contact button (open-type=contact) for customer service
