feat: refactor member to pay-per-use gravity purchase; mv webview to clipboard+browser

- member.vue: rewrite from subscription plans (free/growth/sprint) to
  H5-only pay-per-use gravity purchase with quantity selector + QR code
- user.vue: gravity card replacing quota card, add share/contribute/H5-buy
  entry points, plus gravity acquisition modal (share/contribute/buy)
- share.vue: layout fix (flex column), smarter copyLink with cached URL,
  WeChat timeline hint instead of open-type
- share.controller.ts: add GET /:shareCode redirect route (IP record + 302)
- interview.vue: guest mode fix, H5 buy modal, clipboard copy instead of
  webview for mini-program
- App.vue: handleH5UrlParams for ?token=&buy=gravity auto-login
- composables/useGravityPurchase.ts: reusable gravity purchase composable
- remove webview.vue (no longer used), replace with clipboard+browser flow
- AGENTS.md: sync all above changes, fix duplicate numbering
