test(fusion_accounting_assets): 5 OWL tour tests

Mirrors Phase 1 + 2 tour pattern: HttpCase.start_tour wrappers tagged
'tour' so they skip cleanly when websocket-client is absent. Tours cover
smoke (/odoo loads), the asset list / category list / anomaly list views,
and the depreciation-run wizard form. Bundle is wired via
web.assets_tests.

Verified locally: 5 tests registered, all skip with
"websocket-client module is not installed" (expected — no chromium in
the dev container).
