fix: Skip frequency checks for data collection signals

PROBLEM:
- 1-minute data collection signals were getting blocked
- Overtrading penalty: '30 signals in 30min (-20 pts)'
- Flip-flop penalty: 'opposite direction 1min ago (-25 pts)'
- These penalties don't make sense for data collection

ROOT CAUSE:
- Quality scoring runs for ALL timeframes (needed for analysis)
- But frequency checks (overtrading/flip-flop) only apply to production (5min)
- Data collection signals (1min, 15min, 1H, etc.) shouldn't be penalized

SOLUTION:
- Added skipFrequencyCheck parameter to scoreSignalQuality()
- Set to true for all non-5min timeframes: skipFrequencyCheck: timeframe !== '5'
- Moved timeframe variable declaration earlier for reuse
- 1-minute signals now score purely on technical merit (ADX/ATR/RSI/etc.)

IMPACT:
- 1-minute data collection works correctly
- No false 'overtrading' blocks every minute
- Quality scores still calculated for cross-timeframe analysis
- Production 5min signals still have full frequency validation

FILES CHANGED:
- app/api/trading/execute/route.ts (quality scoring call)
