docs: remove or restore missing reference/http-api navigation page

[azolotov]

Link to a minimal reproduction

https://github.com/vercel/eve/blob/main/docs/meta.json

Steps to reproduce

1. Open docs/meta.json on the main branch.
2. Inspect the Reference section, which lists http-api, typescript-api, cli, and project-layout.
3. Look for docs/reference/http-api.md or docs/reference/http-api.mdx.
4. Observe that no corresponding HTTP API documentation page exists.

Current vs. expected behavior

Current behavior

docs/meta.json includes reference/http-api, but the repository contains no matching Markdown or MDX file under docs/reference/. Consumers that enumerate documentation from the navigation metadata encounter a missing page.

Expected behavior

Every page listed in a meta.json navigation file resolves to an authored documentation page. Either restore the HTTP API page or remove the stale http-api entry from docs/meta.json.

eve version

main (documentation source; not runtime-version-specific)

Environment

GitHub main branch / documentation build. OS, Node.js, and package manager are not relevant to this repository-content mismatch.

Where does the bug occur?

Other

Deployment

No response

Build and runtime logs

Not applicable. This is a static documentation navigation mismatch: `docs/meta.json` references `reference/http-api`, but no matching source file exists.

Additional context

Searches across open and closed vercel/eve issues for reference/http-api and http-api did not surface an existing issue about this missing documentation page.
