rob ee16023b6b Add public strategy subscription system 
Implement a subscription system for public strategies:

Security & Auth:
- Bind WebSocket user identity at connect time (prevents spoofing)
- Add server-side ownership verification for all destructive operations
- Invalidate socket connections on logout
- Add XSS protection with HTML/JS escaping in frontend

Database:
- Add strategy_subscriptions table with proper indexes
- Fix get_all_rows_from_datacache to fall back to DB when cache empty

Backend:
- Add subscribe/unsubscribe endpoints with authorization checks
- Add get_user_strategies (owned + subscribed) and get_public_strategies_catalog
- Propagate indicator_owner_id through strategy instances for subscribed strategies
- Redact strategy internals (code, workspace) for non-owners

Frontend:
- Add "Add Public" button to browse and subscribe to public strategies
- Show subscribed strategies with creator badge and unsubscribe button
- Prevent editing of subscribed strategies (show info modal instead)
- Add public strategy browser modal

Tests:
- Update authorization tests for new subscription-required model

rob 639043b261 Live trading infrastructure functional on testnet 
Key fixes:
- ExchangeInterface: Remove stale entries before creating new exchange connections
- LiveBroker: Optimize get_total_equity() to price only top 10 assets (was hanging on 462 testnet assets)
- LiveBroker: Add fiat currency skip list to avoid failed price lookups
- PythonGenerator: Fix market symbol regex to handle 2-5 char symbols (BTC/USDT)

New features:
- LiveStrategyInstance: Full live trading strategy execution
- Circuit breaker and position limits for live trading safety
- Restart-safe order reconciliation via client order IDs

Verified working:
- Live strategy starts on Binance testnet
- Orders placed and filled successfully
- Execution loop runs with active strategies

rob 6821f821e1 Implement execution loop, paper persistence, and CI pipeline 
Strategy Execution Loop:
- Add tick() method to StrategyInstance for price-driven execution
- Add update() method to Strategies for iterating active instances
- Enable execution loop in received_cdata() to process candle updates
- Add PaperStrategyInstance.tick() with broker price updates

Paper Trading Persistence:
- Add Position.to_dict()/from_dict() for serialization
- Add PaperBroker state persistence (save_state/load_state)
- Add _ensure_persistence_cache() with DB schema migration
- Auto-load/save broker state in PaperStrategyInstance

Runtime Fixes (from Codex review):
- Fix get_user_info() signature mismatch in start_strategy
- Fix live/paper mode handling for stop operations
- Normalize fill event payload (filled_qty/filled_price keys)
- Remove double broker update path (delegate to tick)
- Prevent runtime events from polluting strategy list in UI

CI Pipeline:
- Add GitHub Actions workflow (.github/workflows/test.yml)
- Python 3.12 with TA-Lib dependency
- Syntax checks and 5 critical test suites

Tests: 85 passed
- test_strategy_execution.py (16 tests)
- test_execution_loop.py (17 tests)
- test_paper_persistence.py (19 tests)
- test_backtest_determinism.py (13 tests)
- test_brokers.py (18 tests)
