Feature Request: Level 1 Heatmap (BBO Mode)

Enable the Heatmap for Level 1 users. Since Level 1 provides the BBO (Best Bid/Offer) and Trade Bubbles, the engine can simply render the current BBO price and volume bubbles without the Limit Order depth (Level 2).

Why:

It’s a simple fix that gives traders a clean, visual price-flow history without the "noise" of limit orders.

Low effort, high value—let's make the Heatmap accessible for Level 1!
