📊 Broadcast & Funnel Analytics Improvements

We've made several improvements to funnel analytics and the broadcast index to help you focus on the most important metrics and understand your data better.

: Restored navigation labels in the Funnel Workflow Builder header for English users, with unified button styling across the interface.

: The funnel builder now displays a timeframe label below each funnel step card showing which date range the stats reflect, so you always know what you're looking at.

: Timespan filters from funnel builder stats now pass through to orders and contacts views in the Funnel Workflow Builder when you click stat cards, keeping your context as you dig deeper.

: Added "Viewed Funnel Step at" contact filter with date range support, and the system now shows a "No results found" message for empty filter results.

: Broadcasts index now shows Open Rate and Revenue columns by default—the metrics most people care about. Split Test has been moved to the column toggle (you can always add it back to the view), and broadcasts can now be sorted by send date.
