新增园区详情和成员列表API

新增API：
- GET /admin/park/tenants/{tid} - 园区详情（含统计：成员数/企业数/管理员信息）
- GET /admin/park/tenants/{tid}/members - 园区成员列表（含用户信息）
- GET /admin/companies/{cid}/members - 企业成员列表（含用户信息）

扩展_park_tenant_public函数，增加更多字段：
operator_user_id、city、address、contact、tags、area_m2、
default_company_discount、default_user_discount、created_at
