fix(vip): keep 开通会员更多内容 inside the modal only

The user-center VIP tab rendered pay_user_vip_more in a muted box below the level cards, which the reference theme does not do: zibpay_user_page_tab_content_vip only renders pay_user_vip_desc in the status box, and pay_user_vip_more appears solely in the two modal builders (purchase and existing-member renew/upgrade). The page block stayed invisible while the setting defaulted to empty and surfaced once the zibll default copy landed.

Remove the page-level block; the modal view model and pay-vip.js right-column rendering are untouched.

Verification: regression test locks vip-tab.php free of the more block while the modal path keeps carrying it; node --test tests/**/*.test.cjs 635/635 pass; php -l clean.
