networkDisconnection disabled feature - improve implementation (or ideally remove)

[sei-bstein]

The ConsoleForgeConfig type provides various feature flags that allow end devs to turn off features they don't want to use. One of these is networkDisconnection.

For now, we just implemented this via visibility of various components in the default toolbar. This is an okay stopgap, but if we want to support the feature flag longterm, we should cause it to prohibit the raising of network disconnection events as well (the toolbar is just the interface by which those events tend to be generated).

Alternatively, we only need this feature because a key internal consumer of ConsoleForge doesn't support network disconnection. If we're able to improve that someday, we can remove the flag (assuming we don't have a compelling separate need for it).
