/** Cheque-book detail for the Clerk Dashboard — a fullscreen clerk-styled view of one book, its leaf
 *  register, and the same maker-side leaf actions (stop-payment, revoke, report-lost, cancel-leaf,
 *  mark-used) as the back-office ChequeBookDetailComponent, so a clerk can act on a leaf without leaving
 *  the clerk shell/nav. Every action still goes through the existing maker-checker approval flow server-side.
 *  Each action opens as a popup (ClerkLeafActionDialogComponent) rather than an inline form so it never
 *  pushes the leaf grid around and gets the full dialog width to lay out its fields. */
