[Client] Route cockatrice:// link clicks from chat to the intent chain

A cockatrice:// link clicked in chat is currently handed to the OS (or
does nothing in-process). Clicks now emit a cockatriceLinkActivated signal
that travels ChatView -> Tab -> TabSupervisor -> MainWindow, which feeds
the URL through the same IntentUrlParser the OS activation path uses, so
the join runs entirely in-process. card/user schemes and all other links
behave as before.
