feat(site): link upcoming components to request issues

[sanmaxdev]

Summary

• Add a direct request link to each upcoming post component on the catalog page.
• Prefill the existing feature request issue form with the component slug and proposal text.
• Cover the request-link behavior in the catalog e2e suite.

Verification

• pnpm source:build
• pnpm exec tsc --noEmit
• pnpm lint
• pnpm build
• pnpm exec playwright test tests/e2e/frontend.e2e.spec.ts -g "links upcoming components"

Registry Checklist

• Registry changes keep generated public/r output out of git.
• Component changes update source, manifest, docs, and installer tests together. N/A — site-only catalog link change.
• Payload target code keeps Local API and hook examples transaction-safe. N/A — no Payload target code changed.

Notes

Fixes #127
