Medium Risk
Touches the perps market detail page with new live price subscription logic and a 1s interval timer, which could affect rendering/performance or cleanup behavior if mismanaged; otherwise changes are primarily UI/formatting.

Overview
Improves the perps market detail UI by adding info tooltips for Funding Rate and Open Interest, plus a new Oracle Price row populated from a live subscribeToPrices stream update.

Adds a per-second UTC funding countdown shown alongside the funding rate, and polishes formatting/styling: available balance now displays the numeric value, ROE uses percent formatting, size/margin values are reformatted, and CTA button variants/styles are adjusted (swap primary/secondary and remove custom long/short coloring).
