Its common for the heater hoses to fail in that location. When the engine overheats due to lack of coolant you risk warping the head(s) due to eccessive heat. Once the head warps the head gaskets are unable to do their job.
Murky coolant is to be expected if you neglect to flush the coolant system periodically. But “murky” doesn’t necessarily mean there is oil in the coolant. You can purchase a hydrocarbon test kit to check the coolant for oil contamination.
Although oil can contaminate the coolant in the event of a lifted head or faulty head gasket(s), you shouldn’t lose nearly the entire oil capacity in such a short period of time.
When is the last time you checked your oul level? I wonder if you had a pre-existing issue that caused oil consumption over a period of time that you only caught now as result of the ruptured heater hose.
