Fix T+1 trade overlap issue - complete rewrite

Problem: Original T+1 converter didn't handle position overlap correctly.
When T+1 adjustment extended a trade, new signals during the extended
period were still executed, causing double-counting of capital.

Solution:
- Complete rewrite of t1_converter.py with proper position tracking
- New simulate_t1_trades_v2() function:
  - Processes signals in chronological order
  - Tracks current position and availability
  - Skips signals that arrive during existing positions
  - Correctly calculates T+1 delayed exit times
  - Accurately tracks capital usage (100% position sizing)

Results:
- Before: 16 trades, time overlaps existed, incorrect capital calculation
- After: 14 trades (2 skipped due to overlap), no time overlaps,
         correct +13.55% return vs original +14.80%

Files:
- t1_converter.py: Complete rewrite with V2 logic
- t1_converter_v2.py: Backup of new implementation
- auto_report_long_only_t1.py: Updated to use simulate_t1_trades_v2
