Family Spinner Move to Bottom Navigation on Confirm Transaction

Upon tapping the confirm button on a dark transaction sheet, a loading screen appears with a central logo and a spinner. As the transaction processes, the app transitions to the light-themed main wallet dashboard. During this transition, the central loading element dynamically scales down and travels to the bottom-right corner, morphing into a spinning progress indicator around the floating action button. This maintains visual continuity and context, signaling that the transaction is still processing in the background while letting the user return to the main interface.
