## Grid trading

* Added `POST /api/v5/tradingBot/grid/adjust-investment` to add margin or
  investment to a running spot or contract grid without stopping it.
* The grid order details endpoint `GET /api/v5/tradingBot/grid/orders-algo-details`
  now includes `annualizedRate` and `gridProfit` breakdown fields.
* New WebSocket channel `grid-orders-spot` pushes lifecycle events for spot grid
  bots on the private channel.
