Remove five orphaned HTML templates left behind when slice 8C retired the disk/storage/restore web handlers (storage_handlers.go, handler_restore.go and the /api/storage/* + /api/restore/* routes): storage_init, storage_attach, migrate, migrate_drive, restore. Zero .go references, zero cross-template references, no route, no nav entry; embed is a glob so deletion is safe (14 templates remain, build + tests green). No behaviour change; the deleted pages were already unreachable. Also ships the live demo validation (v0.39.0) writeup in REPORT.md.
