feat(freight-backoffice): render reports from the server-driven catalog

Drop reportConfigs.ts (per-report FE config duplicating the backend) and
the chart-drawing ReportPage. Replace with ReportView: one engine that
renders any report the GET /reports catalog describes — filters, KPI
strip, sortable/paginated DataTable, xlsx/pdf export via blob download.
ReportSection embeds a report inline on any page, scoped by idKey, and
renders nothing if the caller lacks that report's permission.

Sidebar Reports submenu is now built from the live catalog
(sidebar-sections.tsx + App.tsx) instead of a hand-listed key — no FE
edit needed to add or hide a report.
