ibkrcp 0.1.2

ibkr_portfolio_positions(): confirmed field name mappings against the /portfolio2/ endpoint (description, marketPrice, marketValue). Added avg_price and realised_pnl columns. All position fields use null-safe coalescing to prevent data frame construction errors when optional fields are absent.
ibkr_live_orders(): added null-safe coalescing for all order fields, so a missing field in a single order no longer errors the entire call.
Added ibkr_logout() to cleanly terminate an authenticated session.

ibkrcp 0.1.1

ibkr_search_contracts(): fixed incorrect HTTP method (GET → POST) to match the IBKR Client Portal API specification.
ibkr_get_trading_schedule(): removed hardcoded symbol and exchange defaults; both are now required arguments. Function now returns the raw API response instead of a parsed data frame.
ibkr_tickle() renamed to ibkr_ping() and switched to POST per API spec. Authentication check removed from the function — callers handle this logic.
ibkr_auth_status(): fixed incorrect HTTP method (GET → POST).
ibkr_reauthenticate() removed — deprecated by IBKR and unused.
ibkr_get_accounts() renamed to ibkr_portfolio_accounts().
ibkr_get_summary() renamed to ibkr_portfolio_summary().
ibkr_get_positions() renamed to ibkr_portfolio_positions(). Updated to use the /portfolio2/ endpoint; added sort and direction parameters.
ibkr_get_orders() renamed to ibkr_live_orders(). Added filters and force parameters.
ibkr_confirm_order_messages() renamed to ibkr_reply_order().
