Add three Astro markdown pages under docs-site/src/pages/legal/:
- terms-of-service.md -> /legal/terms-of-service
- privacy-policy.md -> /legal/privacy-policy
- acceptable-use-policy.md -> /legal/acceptable-use-policy
All three use the Base.astro layout and render the legal content from
docs/legal/ (synced verbatim). The Base.astro layout already had legal
footer links added previously; this commit also adds a footer section
directly in index.astro for redundancy.
The ToS URL (https://docs.leeworks.dev/legal/terms-of-service) is now
ready to be pasted into the RapidAPI listing (issue #44).
