feat(fusion_accounting_reports): menu + window actions with coexistence group filter

Adds views/menu_views.xml with a Financial Reports root menu (sequence
50) and three sub-items: Open Report... (period picker wizard), Export
to XLSX... (xlsx wizard), and Anomalies (list view of fusion.report.anomaly).

Every menu and the root are gated by group_fusion_show_when_enterprise_absent
so the entire Fusion Reports tree disappears when Enterprise's
account_reports module is installed - the engine, AI tools, and exports
remain available; only the UI hides to avoid duplicate menus.

Includes a window action for fusion.report.anomaly (list,form).
