Highest density of water is when it’s at 4 degrees. Hence it makes sense to me that while increasing pressure, ice melting point should get lower.
However, I’ve been told that at very high pressures it’s possible to have solid ice at 79°C. How is that possible?

At normal atmospheric pressure, yes. At extreme pressures, this no longer holds true.

And even way above that, at least according to https://en.wikipedia.org/wiki/Phase_diagram#/media/File:Phase_diagram_of_water.svg
