feat(giving): keyboard-first Sunday offering batch entry page + routes

- Add MemberQuickAddDialogComponent for fast in-session member creation
- Add OfferingSessionPageComponent: client-side buffer, reconcile totals, date-conflict check, submit to API
- Wire finance/giving-categories, finance/givings, finance/offering-session routes (RoleGuard: finance + super_admin)
- Fix givings-page: replace [total] + data[] with GridDataResult for Kendo v20 server-side paging
