fix: Correct Support/Resistance calculation in enhanced signal scoring

PROBLEM:
- "bad operand type for unary -: 'list'" error
- Line 265 tried to negate a list: support_levels = -support_levels
- _find_peaks() returns a list, not numpy array
- Caused S/R Score to default to 50/100

SOLUTION:
- Changed: support_levels = -support_levels
- To: support_levels = [-s for s in support_levels]
- Negates each element in the list individually

IMPACT:
- S/R Score now calculated correctly
- Enhanced Score will be more accurate
- Better trade filtering
