Build BoxtOut AddressSelectionUI

Address Selection UI sync

The functionality for the Address selection has been built. At the moment it does not match the styling from the designs. See attached.

In this ticket we need to:

• Build the AutoCompleteListItem to match the design
• Add the animation to move the "search input" higher when the user focus's on it
• Hide the keyboard and auto complete results when user selects a location
• Center the floating continue button on the Scaffold
• Hide the floating continue button until we have selected a value

The PR for this ticket will be reviewed in a FilledStacks episode so keep it tight! Keep things neat :)

I hope someone does it lol. Otherwise I'm talking to myself. Which happens a lot 😄
