Make connect dialog list entries show up in white on iOS dark mode

Looks like the Connect Dialog list entries also need some work to be compatible with a dark mode theme. I suspect those texts are set specifically to black instead of being left to default.

No file or test is identified in the issue. Start by locating the iOS Connect Dialog list implementation and reproducing it with an iOS dark mode theme; done means the list entries are visibly white and remain readable in dark mode.
