fix: prevent scrolling to account list item on send page

[bfullam]

Description

Opening the send page scrolls down to the currently selected account. On a wallet with 6+ accounts, this scrolls so far that the more relevant sending UI is out of view. This PR prevents the scrolling behavior, keeping the relevant UI in view.

Manual testing steps

1. On a wallet with 6+ addresses, select the last address on extension
2. Click the Send button
