🤖 Augment PR Summary

Summary: This PR adds a focused regression check for the collaboration server's GraphQL authorization header.
Changes:

• Extracts Apollo/Hasura client creation into a reusable collaboration-client module.
• Updates the Hocuspocus server to obtain its per-context client from that module.
• Adds a local HTTP-server test that verifies the scoped JWT is sent as a Bearer token.
• Adds a Vite SSR test build and ignores its generated output directory.

Technical Notes: The client retains no-cache and GraphQL error-handling defaults while allowing the test to inject its endpoint.

Pull request overview

This PR adds a small regression test harness for the collaboration server’s Hasura GraphQL client, aimed at preventing a repeat of the “No Authorization header found” failure mode described in issue #959.

Changes:

• Refactors collab server GraphQL client creation into a dedicated createCollabGqlClient() helper.
• Adds a Node/Vite-built regression test that asserts the outgoing GraphQL request includes the expected Authorization: Bearer … header.
• Wires the test into javascript/package.json via a new test:collab-graphql-auth script and ignores the build output directory.
