Two-tiered activity timeline

This component displays a timeline of recent activity in a two-tiered layout. The top-level groups activity by day, with the current day highlighted at the top. Within each day, individual activity items are shown in a table with amount, client, and link for more details. The timeline uses utility classes like py-5, text-sm, and flex to control spacing, typography, and layout. The multi-column layout is achieved using flex, table, and grid column classes.
