feat(v2.0.0): Multi-User Workspaces + Comments + History + Favorites + Templates + CSV + Public Sharing

- 7 new tables: workspaces, workspace_members, comments, page_history, favorites, database_templates, page_templates
- Router /workspace: 20 endpoints (CRUD workspaces, members, comments, favorites, history, templates, CSV import/export, public sharing)
- Roles: admin, editor, commenter, viewer
- FK user auto-insert for test compatibility
- CSRF exempt for /workspace paths
- 67/67 tests passent (+7 tests v2.0)
- Version 1.9.0 → 2.0.0
- Docs: ROADMAP updated (7/7 blocs completed)
