Adds the read-only paper-trading page (/paper-trading): settled-only P&L KPIs (net profit, ROI, hit rate, open count) plus a per-bet ledger table, with a Forward-test nav entry under Analysis. PaperTradingService batches the event-title join (no N+1) and folds settled bets into the summary. Also hardens PaperTradingWorker (review finding): settle now runs in its own catch so a transient settle failure can't advance the since-marker past an open window — the window replays until its opens succeed. - IPaperTradingService / PaperTradingService / PaperTradingVm + PaperBetRowVm. - en/ru resx (full parity), service registration, nav entry. - 2 service tests: empty ledger + settled-only aggregation incl. title fallback.
