Refocus on XAU/USD: add momentum indicators, tune TP, exhaustion block

Strip EUR/USD, GBP/USD, USD/JPY pairs and strategies from entire codebase.
Add 3 new scored indicators (ROC, Keltner/TTM Squeeze, ADX slope) and
enable MACD-as-pillar + divergence detection for early trend entry.
Introduce "transitioning" regime (ADX < 25, slope > 3.0) to catch trend
births before ADX confirms. Gold-specific composite weights per regime.

Tune TP multipliers: quality-tiered scaling (A+/A get 1.5-2.0x ATR via
XAU ATR method, B/C use swing-level targeting). Backtest: +24R total,
65% WR, PF 1.12 over 365 days.

Add momentum-confirmed exhaustion block: hard-reject trades when 2+
static exhaustion signals fire AND ROC/MACD confirm fading momentum.
Prevents late trend entries without killing strong trend trades.

Telegram: simplify buttons to timeframe-only labels, add "Scan All TFs"
multi-timeframe summary, add /scan command, fix BB/KC level breach keys,
fix price formatting (.2f for gold), fix deprecated asyncio call, fix
"1 pairs" grammar and 60s/30s dashboard refresh mismatch.
