Migrate projects to Hivecom OAuth (Supabase) Authentication

[dolanske]

Migrate users from their project-related databases existing hivecom.net users and allow authenticating via the main website. Ideally, we'd remove all logins from the related projects and use hivecom.net users as the only source of truth for its userbase.
