Description
We fetch the symbol properties from LEAN (symbol_properties_database.json) which can be out of date for some reason, resulting in errors such as
New Order Event: Time: 05/22/2025 00:00:00 OrderID: 3 EventID: 1 Symbol: BNBUSDT Status: Invalid Quantity: 1.05801 Message: Bybit Order Event: ByBitApiClient request failed: [200] OK, Content: {"retCode":170148,"retMsg":"Market order amount decimal too long","result":{},"retExtInfo":{},"time":1747872000379}, ErrorCode: 170148
The SPDB has a minimum price variation of 0.00001, allowing 1.05801, but the actual variation is 0.0001, so the quantity should be 1.0580.
We should pull this information daily and update the SPDB to avoid these errors.

Research direction
Start by locating symbol_properties_database.json and the existing Bybit integration entry point. Trace how LEAN symbol properties are loaded and determine where a daily refresh would fit; done means current Bybit precision is reflected and the reported invalid-quantity case is prevented.
