fix: Home redirects local accounts to /local-workspace + sidebar Workspace section

- Dashboard '/' checks user_oauth_tokens for Gitea connection
- Local accounts (no Gitea token) redirect to /local-workspace
- Sidebar: Workspace section above Meetings with 'My Workspace' link
- Local users no longer see Gitea projects on Home page
