TB 43465: Replace TorConnect.canBeginBootstrap with TorConnect.canBeginNormalBootstrap to distinguish it from TorConnect.canBeginAutoBootstrap.

- - - - - 481be29c by Henry Wilkes at 2025-02-27T12:38:32+00:00 fixup! TB 27476: Implement about:torconnect captive portal within Tor Browser

TB 43465: Show the urlbar Connect button when the user might want to return to about:torconnect.

Instead of hiding the button when canBeginNormalBootstrap is false we show it as a plain button. Instead we hide it only when we are already bootstrapped.

We also avoid initialising the button when TorConnect is not enabled.

We also update TorConnect.open:

1. Do not re-open about:torconnect if we are already connected. E.g. when the user selects "Connect" in a bridge dialog but we are already connected by the time the settings are applied. 2. Do not call TorConnect.startAgain when receiving a "hard" request. Only the bridge dialogs make this request, and they would have already triggered startAgain by changing the bridge settings.
