feat(membership): 体验会员补充 referral_commission 权益 + 前端动态加载权益列表

- DatabaseInitializer: 迁移341 BASIC features JSON 补 referral_commission
- MembershipService: BASIC 可用功能加入 referral_commission
- schema.sql: membership_levels 种子数据同步
- membership/index.vue: 动态加载权益功能列表（免费用户展示 BASIC 体验会员功能）
- utils/api.js: 新增 getMembershipBenefits 接口封装
- ContentRecommendService: 改用 selectCompletedArticleIdsByChild 查询已读文章（与文章列表过滤逻辑一致）
