fix(p0): resolve schema migration gate, controller NPE, auth check, WeChat template message support

- DatabaseInitializer: recordSchemaVersion 3→5, create emotion_alert + mental_health_screen tables
- EmotionAlertController: fix NPE in condition checks, add admin role auth check, add /api/mind/admin/alert/list and /api/mind/admin/alert/resolve endpoints
- WechatService: add sendTemplateMessage() for alert push via WeChat template messages
- application.yml: add alert-template-id config

Implementation checklist complete:
  ✓ DatabaseInitializer.java: version gate + DDL
  ✓ EmotionAlertController.java: NPE fix + auth + admin endpoints
  ✓ WechatService.java: sendTemplateMessage()
  ✓ application.yml: alert-template-id
