feat: v11.2 Indicator Score Bypass System (SCORE:100)

- Added indicatorScore bypass in check-risk endpoint (lines 91-104)
  * When indicatorScore >= 90, bypasses quality threshold check
  * Logs: '🎯 INDICATOR SCORE BYPASS: Score X >= 90, bypassing quality check'

- Added indicatorScore to ExecuteTradeRequest interface
  * Optional field: indicatorScore?: number

- n8n workflow updated (via API):
  * Parse Signal Enhanced: Regex extracts SCORE:(\d+) from alert
  * Check Risk1: Passes indicatorScore in request body
  * Execute Trade1: Passes indicatorScore to bot

- v11.2 Indicator sends SCORE:100 in all alerts
  * Indicator already filters to PF 2.507 profitable setups
  * Bot quality scoring is redundant for pre-validated signals

Signal Flow:
TradingView v11.2 (SCORE:100) → Webhook → Parse Signal → Check Risk1 (bypass) → Execute Trade1 → Trade Executed

Verified: Dec 26, 2025 - Full webhook test successful
- Execution 70758 completed
- SOL-PERP LONG opened at $124.01
- Drift and DB positions match (12.86 SOL, $1,597)
