Summary

Refactor console stop-message endpoints to inject the current account id with with_current_user_id.

This PR replaces direct current_user.id usage in stop-message endpoints where only the user id is needed. Handlers that still require the full Account object are kept unchanged.

Fixes #36585

Screenshots

Not applicable. This is a backend refactor and does not change the UI.

Pull request overview

Refactors console stop-message endpoints to inject the authenticated user’s ID via @with_current_user_id, avoiding direct dependency on current_user where only the ID is needed.

Changes:

• Added @with_current_user_id to stop endpoints and updated handler signatures to accept current_user_id: str.
• Replaced user_id=current_user.id with user_id=current_user_id in stop-task calls.
• Removed current_user type assertions in the explore stop endpoints (and one of the debugger stop endpoints).

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 2 comments.

api/controllers/console/app/completion.py	Applies @with_current_user_id to debugger stop endpoints and switches stop-task calls to use the injected user id.
