WalletConnect: Add app preview & permissions UI

[DRadmir]

Replace header AsyncImageView with AssetPreviewView and add AppPreviewModel to represent app preview data. Expose appPreview and permissions from SignMessage and ConnectionProposal view models and render a permissions section in ConnectionProposalScene. Add PermissionItemView, adjust ListItemImageStyle to support foregroundColor and update ListItemView to pass it through. Include spacing/content margin tweaks and add new localization keys for portfolio and permissions across languages.
