fix: cleanup_all_camofox_sessions respects managed persistence (#6820)

When managed_persistence is enabled, cleanup_all now only clears local
tracking state without sending DELETE requests to the Camofox server.
This prevents persistent browser profiles (cookies, logins, localStorage)
from being destroyed during process-wide cleanup.

Ephemeral sessions still get full server-side deletion as before.
