fix: Minors fixes for issues found when using StatusFloatingButtons and implementing new SendModal (#748)

1. Fix the issue of floating buttons having incorrect color in Dark theme
2. Added balances param in StatusAssetSelector. ideally should be removed in another task as it is not the correct place for business logic
