{#
  SETTINGS · Configure per-agent save banner (R4c). Swapped into a row's
  #cfg-saved-<name> slot after POST /settings/configure. A compact inline
  confirmation (or error) for that one agent.

  NOTE: the override is saved CONSOLE-LOCAL ONLY (app-DB — the fast display/routing
  overlay). The registry is NOT touched on save (feature-gap #81, the
  CTO's reversed decision); committing the config to the Cortex registry is the explicit
  "Promote to registry" action in the SPA config modal.

  Context:
    saved          : truthy on a successful persist
    saved_error    : error string (when the save failed)
    cfg_agent      : the agent name saved
    cfg_effective  : the agent's post-save override dict ({} when cleared)
    cfg_has_override : whether any override remains after the save
