Solve a final minor-should-rescale edge case
When the minor has the same scaling as the major in a given direction we should still do back-scaling against the major-target and previous minors to avoid strange edge cases where only the target-major might not be shifted correctly to show an matched intersect point? More or less this just meant making the y-mxmn checks interval-inclusive with `>=`/`<=` operators. Also adds a shite ton of detailed comments throughout the pin-to-target method blocks and moves the final major y-range call outside the final `scaled: dict` loop.log_linearized_curve_overlays
