fix: log parser duplicate position bug and selective CI/CD deployment

- Log parser: fix entry dedup to check direction instead of price tolerance,
  preventing duplicate OPEN trades for the same position
- Log parser: close all OPEN trades on position close, delete stale duplicates
- Jenkinsfile: detect changed files and only build/deploy affected services,
  allowing dashboard-only changes without restarting the bot
