Rename and reposition the two VIP modal copy settings to match the zibll reference backend, drop dead renew/upgrade desc config, and align copy defaults.
- pay_user_vip_desc: modal top intro -> 会员介绍, textarea -> input (one-line), zibll help text, default copy from zibll
- pay_user_vip_more: bottom note -> 开通会员更多内容, rows 4 + sanitize_type html (HTML was stripped on save), zibll help text and three-div default
- Both fields move from the member-level group to a new 界面文案 (modal-copy) group at the end of the VIP section; dependsOn any-of-two-levels adapted from zibll's pay_user_vip_1_s dependency
- Copy defaults synced in three places (SPA schema, PHP schema, PaymentRuntime fallbacks, since Settings::get_all() does not merge schema defaults): 黄金会员/钻石会员, 尊享专属特权, zibll four-item equity list
- Remove vip_renew_desc / vip_upgrade_desc: AKSRT has no renew/upgrade card render surface (render_vip_card takes no type) and zero consumers repo-wide; zibll renders them on page-level cards only
- pay_user_vip_1/2_equity and pay_vip_pass_charge_desc gain sanitize_type html so admins no longer lose list/HTML markup on save
Verification: new tests/widget-system/vip-modal-copy-fields.test.cjs (6 contract tests); node --test tests/**/*.test.cjs 634/634 pass; php -l clean on both changed PHP files; assets/admin npm run build succeeds
