feat: add 28 GraphQL mutations across storage, info, docker, and new settings tool

- storage: flash_backup mutation (initiates rclone flash backup, destructive)
- info: update_server and update_ssh mutations
- docker: 11 organizer mutations (create_folder, set_folder_children,
  delete_entries, move_to_folder, move_to_position, rename_folder,
  create_folder_with_items, update_view_prefs, sync_templates,
  reset_template_mappings, refresh_digests); delete_entries and
  reset_template_mappings added to DESTRUCTIVE_ACTIONS
- settings: new unraid_settings tool with 9 mutations (update,
  update_temperature, update_time, configure_ups, update_api,
  connect_sign_in, connect_sign_out, setup_remote_access,
  enable_dynamic_remote_access); registered in server.py
- tests: 82 new tests (28 settings, 23 docker organizer, 7 info, 6 storage
  + 18 existing fixes for notification regex and safety audit list)
- bump version 0.3.0 → 0.4.0 (11 tools, ~104 actions)
