Fix JuliaFormatter line splits across DelayDiffEq.jl

- Combine split arithmetic expressions (integrator.tdir * integrator.t)
- Combine split function constructor calls in fpsolve utilities
- Combine split test assertions for better readability
- Keep semantically related expressions on single lines under 120 chars

This follows Catalyst.jl PR #1306 formatting guidelines to improve readability
by avoiding unnecessary line splits that make code harder to follow.
