The PADD is totally fine to come onboard, though it won't be able to connect up with either the network from home, or the Barge network (retaining its storage capabilities is completely fine, though).
The scanner is also fine to come onboard, though you're correct to assume that it wouldn't be able to diagnose issues with Barge tech or problems caused by the Barge (ex. floods). Whether or not it works on magic-based characters can be up to the players of those characters, and you're free to assume that any wonkiness or inconsistency that results from this (ex. if one player gives permission for their character, but another player doesn't give permission for their similar character) are either caused by Barge interference, or just the natural friction of tech vs. magic.
The replicator is also also fine to stay in her cabin, but yes, if it needs specific consumable supplies she would need to provide those to keep it working (and possibly need to make Admiral requests for them because those would be harder to get than kitchen foodstuffs/etc in a port.)
