Why was it implemented this way?

The wallet/bookmark selector pages had 3 issues: inconsistent empty state styling, whole-widget scrolling instead of list-only scrolling and non-unique icon for "Recent wallets".

• Created a shared EmptyListIndicator component (components/EmptyListIndicator/) with icon, title, and optional message — matching the activities page pattern. This replaces the old EmptyListIndicator (children-based, no description text) and the inline TransactionHistoryEmpty implementation.
• Added useListHeight to BookmarksPage, RecentWalletsPage, and ConnectedWalletsPage so the list area scrolls internally rather than the entire widget.
• Updated BookmarksListContainer to use flex-based layout (flex: 1; minHeight: 0; overflow: auto) instead of hardcoded min-heights, so the button stays pinned and the list fills available space.
• Added description messages for all three wallet empty states and updated the transaction history empty message to be action-oriented.
• Replaced the History icon with AccountBalanceWalletIcon for the recent wallets button and empty state.
