refactor: remove NodeHttpAdapter in favor of @constructive-io/fetch

The ORM client's FetchAdapter already uses createFetch() from
@constructive-io/fetch, which handles *.localhost DNS rewriting and
Host header preservation in Node.js. The separate NodeHttpAdapter
(using node:http/node:https directly) is redundant.

- Remove node-fetch.ts template and all generated node-fetch.ts files
- Remove generateNodeFetchFile() from utils-generator
- Simplify executor generators to always use { endpoint, headers }
- Remove nodeHttpAdapter config plumbing from generate.ts
- Deprecate nodeHttpAdapter option in config types
- Update all 4 SDK executor.ts files to use endpoint/headers

The external API (createClient, getClient) is unchanged — consumers
pass endpoint + headers, and FetchAdapter handles the rest.
