Detailed Description

Test that on-demand orbital progress produces the expected position after a quarter orbital period.

Starting at offset = 0 (ascending node), after T/4 the satellite should have advanced 90 degrees along its orbit. This is equivalent to the LeoOrbitalOffsetTestCase result (offset = 90 degrees at t=0), but verified through time evolution rather than initial offset.

At T/4, Earth rotation causes a small longitude drift that must be accounted for in the expected position.
