docs: Add privacy policy links to footers

[claude]

Requested by Ben Cook · Slack thread

Before: neither footer links to the privacy policy. The marketing/homepage footer shows only "Built by Invertase" + copyright, and the hosted-docs footer shows the "docs.page by invertase.io" attribution plus per-project social links — no privacy link anywhere.

After: both footers show a subtle "Privacy" link pointing to https://use.docs.page/legal/privacy — one on the landing page footer, and one on every hosted docs page footer.

How

• app/src/components/homepage/footer.tsx — adds a "Privacy" anchor next to the existing "Built by Invertase" link in the same left-hand flex items-center gap-4 group, reusing the exact sibling styling (text-sm text-neutral-400 hover:text-foreground). No target/rel since it points to our own site.
• app/src/components/footer.tsx — adds a "Privacy" anchor alongside the "docs.page by invertase.io" attribution, styled to match the sibling links (underline underline-offset-5 hover:text-foreground), with a · separator.

Both links use the absolute URL https://use.docs.page/legal/privacy. This is required for the hosted-docs footer: hosted pages are served under an owner/repo/... path, so a relative /legal/privacy would resolve under the publisher's namespace and 404.

Based on integrate/docs-rewrite rather than main, because that's where the privacy policy page lives (#500).
