Add summary statistics table to UI for Footprint candles

[TrendoBoom]

Feature Request

Add a new summary table feature in Chartink UI that displays key candle statistics for Footprint and market analysis. The table should include the following columns for each candle or time period:

• Volume: Total traded volume
• Volume Change %: Percentage change in volume vs previous candle
• Buy Volume: Aggressive buy volume
• Buy Vol %: Buy volume % of total volume
• Sell Volume: Aggressive sell volume
• Sell Vol %: Sell volume % of total volume
• Delta: Buy volume - sell volume
• Delta Change %: Percentage change in delta vs previous candle
• Min Delta: Minimum delta within candle
• Max Delta: Maximum delta within candle
• POC: Point of control (price level with max volume)
• HL Range: High-Low range of candle
• Signal: Signal value (e.g. Delta Divergence, Delta Drop, Delta Rise...)

Example :

Requirements:

• Add table in UI below or beside Footprint chart
• Table should update dynamically for selected time frame/data
• Table columns should match above specification
• Implement column sorting and filtering where feasible
• Calculation logic may be reused/extended from backend (see core/fyers/processor.py and docs)
• Signal column should be configurable for future expansion

• Existing issue: Add option in UI for configuring Footprint placement (buy right, sell left)
