fix: HTML report extraction and backtest pipeline reliability

- fix: inactivity watchdog now waits 30s for HTML report then kills
  terminal64.exe unconditionally — ShutdownTerminal=1 does not cause
  MT5 to exit on Wine/macOS; relying on natural exit caused all runs
  to fall back to journal extraction
- fix: tester agent log deduplication — each deal is written twice in
  the log; use HashSet to skip already-seen deal numbers
- fix: position tracker for entry direction inference — infer "in"/"out"
  from per-symbol signed lot accumulation instead of guessing
- fix: is_closed_trade() no longer gates on profit!=0.0 — journal deals
  have profit=0.0 legitimately; the old gate hid all 140 deals from
  list_deals
- fix: log file selection priority — prefer Agent-127.0.0.1 over
  Agent-0.0.0.0 (startup-only log), tiebreak by file size
- feat: launch_backtest default shutdown=true; inactivity_kill_secs
  default 120s exposed as tool parameter
- feat: report DB stores deals in SQLite; analytics resolve by
  report_id / report_dir / latest

Verified: 1-month DPS21/XAUUSD.cent/M5 backtest produces full HTML
report with all metrics (win_rate=70%, profit_factor=0.77, sharpe=-3.61,
max_dd=6.93%) and all 17 analytics tools returning real data.
