RuntimeFallbackBadge.tsx calls useToast() unconditionally, but the
ActiveAgentsPanel.test.tsx and AgentsView.test.tsx render helpers never
wrapped the component under test in a ToastProvider, causing every mount
that transitively renders RuntimeFallbackBadge to throw
'useToast must be used within ToastProvider'.
Adds renderPanel()/renderView() helpers (matching the existing
RuntimeFallbackBadge.test.tsx pattern) that wrap render(...) calls in
ToastProvider, and routes every render call site in both files through
them. No test assertions or fixtures were changed.
Fixes 12/15 ActiveAgentsPanel.test.tsx failures and ~96-108/132
AgentsView.test.tsx failures.
