Data Views: refreshed overview, persistent timeframes, and real-time refresh

The Data product surfaces in the dashboard have been rewritten so analytics feels live and remembers your context.

What you will see:

• Data Overview — The overview page now handles organization and workspace switches without losing your filter, refreshes via the new realtime API, and respects a workspace-scoped secret key for embedded views.
• Persistent timeframe — Your timeframe selection is persisted across the Data pages, so jumping from Views to Engagement to Errors no longer resets your range.
• Time-series timestamp fix — A long-standing bug where time-series points were offset by a bucket boundary has been fixed.
• Workspace data refresh — dataProduct now refreshes correctly when you switch organizations or workspaces, including encoding-minute totals.
• Granularity persistence removed — The dashboard no longer fights the server when picking a default granularity; we honour what the API returns and only override on explicit user action.
• Scatter graph for Data Views — A scatter graph type was added for power users who want to spot outliers in their playback fleet.

If you embed Data Views via the workspace secret key, the new realtime endpoint is backwards-compatible.
