Two congruent right circular cones each with base radius \(4\) and height \(10\) have their axes of symmetry intersecting at right angles at a point inside the cones, a distance \(4\) from the base of each cone. A sphere with radius \(r\) fits within both cones. Determine the maximum possible value of \(r^2\), and express this as a reduced fraction \(\frac{m}{n}\) where \(m\) and \(n\) are coprime integers. Find \(m+n\).
