Pro tier upgrade: quant rearchitect + WebSocket level-breach monitor

- Restore XAU/USD (Pro plan), drop USD/CAD, raise rate limit to 55/min
- Reduce signal engine to 4 uncorrelated pillars (EMA, RSI, BB, Candlestick)
  with regime-adaptive weights (trending boosts EMA, ranging boosts RSI+BB)
- Add structure-based S/R (swing highs/lows) for trade setup targeting
- Fix confidence death spiral: all adjustments now additive, not multiplicative
- Dynamic R:R trade setup: SL behind swing level, TP at next structure level,
  reject if R:R < 1.5
- Fix news engine for all 4 pairs (was hardcoded to USDJPY)
- Add WebSocket monitor: streams live ticks, triggers M15 scan on level breach
  with 5-min cooldown per pair — catches breakouts between candle boundaries
- Add correlation filter (EUR/USD+GBP/USD, XAU/USD+USD/JPY exposure warnings)
