refactor: Replace redesign confirmation BottomModal with BottomSheet

[digiwand]

Description

• Replaces BottomModal with BottomSheet in redesign Confirm page
  • Add scroll support
  • Remove min height 70% to prevent redesign Confirm page from showing excess space
  • Allow BottomSheet styles (rounded corners, footer bottom styles, and device padding detection padding) rather than custom BottomModal styles
• Add BottomSheet isBackgroundAlternative prop
  • Added BottomSheet footer isBackgroundAlternative prop
  • Note: I think we don't need the additional background colors for header and footer since the parent, BottomSheet animated view sets the background color. Once I removed them, it triggered many snapshot tests and code owner reviews from 5 additional teams. I reverted this in favor of the explicit isBackgroundAlternative prop
• Update BlockaidBanner to remove surrounding margin to allow for better reusability
  • Replace BlockaidBanner instances margin overrides with surrounding container margins
• Fix TransactionReview BlockaidBanner negative padding → turn to positive padding to allow space between next element
