The shadow book toggle saved on change and the numeric fields on blur, inconsistent with every other admin panel (which stages edits behind a Save button). Stage all four fields in local state and commit them together on Save, with an unsaved-changes hint. This also makes enabling the live-trade toggle a deliberate two-step action rather than an unguarded single click. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
