fix: 空基 FireEvent.MuzzleVelocity=0 + 空基弹道单元测试

Browse Source 
- GenerateFireEventsAt: 空基时 MuzzleVelocity=0（而非800）
- 新增 AirBased_FireTime_EarlierThanArrival 验证提前量
- 新增 AirBased_FireTime_EarlierThanGroundBased 验证空基更早
- 新增 AirBased_NoMuzzleVelocityInFireEvent 验证 MuzzleVelocity=0
- 空基弹道计算本身正确（recommendedTiming - flightTime - fallTime）
