[Fix] Deployment images return 500 after release-history update

What changed

• Removed the repository-root changelog from Next.js output-file tracing so standalone builds retain the transitive dependencies of external server packages.
• Copied CHANGELOG.md directly into the final application image at the path used by release history.

Why this change was made

PR #1893 added ../../CHANGELOG.md to the web app's tracing includes. The first two publish runs after that change failed deployment acceptance because the standalone image omitted transitive dependencies for ioredis, pino-pretty, and bullmq, causing the web smoke request to return HTTP 500.

Impact

Deployment images can load all traced server dependencies while continuing to serve release history from the bundled changelog. A clean production web build, focused release-history tests, type checks, lint, and the full pre-push suite passed. Docker-backed image and acceptance validation could not run locally because the sandbox does not expose a Docker socket; the publish workflow will exercise that exact path.
