Fix workspace reconnect playwright tests after toast move

Test #1 was asserting agent-reconnecting-toast on a workspace with no
agents — but commit 1daa1314 moved the reconnect indicator from the
workspace banner into the per-agent panel toast. Create an idle agent
and navigate to it so the agent panel mounts before dropping the
daemon gate.

Test #2 regex still pinned the old "Connecting to localhost" copy;
commit c534c857 tightened it to just "Connecting" with the hostname in
the description. Match the new title plus the existing offline copies.
