Harden Telegram bot, add EUR/GBP strategies, parallelize scans

Telegram reliability: rate-limited sends (1 msg/s), dashboard lock,
WebSocket JSON/price error handling, markdown escaping, level cache
TTL, cooldown cleanup, breach task tracking, graceful shutdown.

Telegram speed: parallelize 3-pair scans with asyncio.gather(),
increase thread pool 2→4, parallelize boot-up initial scan.

Strategy: add EUR/USD and GBP/USD pullback-buy strategies with
per-pair configs, optimize XAU TP to 0.9×ATR, block hours 8/9
for XAU and hour 17 for GBP.

Backtest: add --max-hours flag to evaluate.py for time-exit support.
