refactor: distribute lab-init.js into 34 engine files

lab-init.js: 4098 -> 543 lines (infrastructure + THEORY only) Each sim's _open*() + UI helpers moved to its engine file: graph.js, projectile.js, collision.js, magnetic.js, triangle.js, geometry.js, trigcircle.js, gas.js (molphys), coulomb.js, circuit.js, reactions.js (chemistry), newton.js (dynamics), chemsandbox.js, celldivision.js, photosynthesis.js, angrybirds.js, quadratic.js, normaldist.js, graphtransform.js, pendulum.js, equilibrium.js, thinlens.js, mirror.js, isoprocess.js, titration.js, refraction.js, probability.js, bohratom.js, electrolysis.js, waves.js, crystal.js, orbitals.js, stereo.js, hydrostatics.js All 34 engine files syntax-checked OK.
