Bug: trade_order_generators.js set skipAdditionalParsing=true which
caused json_base_generator.js to return early before processing <next>
sibling blocks. This meant set_flag and other blocks connected after
trade_action were silently dropped from the JSON.
Fix: Removed the unnecessary skipAdditionalParsing flag. The code path
it was meant to protect was already in an else branch, so the flag
served no purpose and broke <next> block handling.
Also includes minor fixes to Strategies.js and backtesting.js from
earlier session work.

Exchange.py:
- Add get_trading_fees(symbol) - fetches fees from market data
- Tries user-specific fees for authenticated users (fetch_trading_fees)
- Falls back to market data (public)
- Returns maker/taker rates with source indicator

ExchangeInterface.py:
- Add get_trading_fees() - routes to appropriate exchange

trade.py:
- Update new_trade() to fetch actual fees from exchange
- Uses taker fee for market orders, maker fee for limit orders

1. Paper equity calculation (High):

- Previously only added unrealized_pnl, missing position principal
2. Buy affordability checks (High):
- place_order() now uses execution price including slippage for market orders
- Uses limit price for limit orders instead of current price
- Prevents orders that would drive cash negative
3. ExchangeInterface price stubs (High):
- get_trade_executed_price() now handles order_price=0.0 (market orders)
- Falls back to current price or entry price when order_price is zero
4. Determinism hash strengthening (Medium):
- Hash now includes full trade sequence with individual trade details
- Added test for different trade sequences with same totals
5. Live mode consistency (Medium):
- Factory now falls back to paper trading with warning instead of raising
- Consistent behavior between factory.py and Strategies.py
Added test: test_paper_broker_equity_calculation to verify fix#1
