refactor(market): extract price chart into mktDrawPriceChart
Move the ~250-line chart block (interval strip + 24h stats + refresh, plotted curve with grid/area-fill/hi-lo+time labels/hover crosshair+tooltip, empty state) out of RenderMarketTab into mktDrawPriceChart(MktCtx), recomputing cheap locals and reading the precomputed series via the ctx. Drop the now-unused hs/pad locals. Verbatim body. No behavior change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
