Configure a user agreement that users must accept before uploading files

[paullizer]

• User Agreement for File Uploads
  • Global admin-configurable agreement that users must accept before uploading files to workspaces.
  • Configuration Options: Enable/disable toggle, workspace type selection (Personal, Group, Public, Chat), Markdown-formatted agreement text (200-word limit), optional daily acceptance mode.
  • User Experience: Modal prompt before file uploads with agreement text, "Accept & Upload" or "Cancel" options, daily acceptance tracking to reduce repeat prompts.
  • Activity Logging: All acceptances logged to activity logs for compliance tracking with timestamp, user, workspace type, and action context.
  • Admin Access: Settings accessible via Admin Settings → Workspaces tab → User Agreement section, with sidebar navigation link.
  • Files Added: user-agreement.js (frontend module), route_backend_user_agreement.py (API endpoints).
  • Files Modified: admin_settings.html, route_frontend_admin_settings.py, base.html, _sidebar_nav.html, functions_activity_logging.py, workspace-documents.js, group_workspaces.html, public_workspace.js, chat-input-actions.js.
