📄 Description

Describe your changes

Explicitly set Path: "/" on the session cookie written by the reverse proxy's auth middleware.

Without an explicit Path, browsers default to the path of the request URI that set the cookie (MDN reference). This means a user authenticating at example.com/app/page gets a cookie scoped to /app, and subsequent requests to sibling paths like /api or /_app/* are treated as unauthenticated — breaking SPAs, share links, and any service that fetches resources from multiple top-level paths.

This was originally flagged by CodeRabbit during review of #5587 as an outside-diff comment, but wasn't picked up before merge.

Without an explicit `Path`, browsers default to the path of the request URI that set the cookie ([MDN reference](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Set-Cookie#pathpath-value)).
