🎨 Add cookie-based auth in publish proxy (#15692)

* chore(publish-auth): Add TODO for cookie-based auth in publish proxy

A TODO comment was added to indicate future implementation of authentication using cookies in the PublishServiceTransport RoundTrip method.

* 🎨 Add session-based authentication for publish proxy

Introduces session management using cookies for the publish reverse proxy server. Adds session ID generation, storage, and validation in kernel/model/auth.go, and updates the proxy transport to check for valid sessions before falling back to basic authentication. Sets a session cookie upon successful basic auth login.

* 🐛 Fixed the issue of repeatedly setting cookies

* 🎨 Dynamically remove invalid session IDs

* ♻️ Revert changes in pnpm-lock.yaml
