Fix formatting line splits in DiffEqFlux.jl

Fixed 6 instances of unnecessary line splits across multiple files:
- src/ffjord.jl: Fixed 2 mathematical expressions (logpz calculation and cat function call)
- src/multiple_shooting.jl: Fixed 2 arithmetic expressions with continuity_loss
- docs/src/examples/augmented_neural_ode.md: Fixed 2 identical arithmetic expressions in random_point_in_sphere function

All changes follow Catalyst.jl PR #1306 guidelines to improve readability
by keeping semantically related expressions on single lines while staying
under 120 character limits.
