Only persist Lobsters login cookies after the WebView proves the
session is authenticated, and treat anonymous lobster_trap cookies as

embedded login flow cannot silently restore a prior session.

tracking one timestamp plus an edited flag instead of fabricating a
creation time we no longer receive.
