* Check runner trades for virtual take-profit hits and set SL to breakeven if crossed.
*
* Runner trades are assumed to be opened with no TP and a special comment in the format: "runner_tp:1.10500".
* This method parses that comment to determine the virtual TP, and if price has crossed it, moves SL to breakeven ± buffer.
*
* param symbol: Trading symbol to check positions for
* param runner_magic_no: Magic number assigned to runner trades
* param buffer_points: Buffer to add/subtract from entry price when setting SL (in points, converted internally)
