♻️ Convert snap-points components to modern rumext format

Migrate snap-point, snap-line, snap-feedback, and snap-points from
legacy mf/defc format to modern * suffix format. This enables
optimized props handling by the rumext macro, eliminating implicit
JS object wrapping overhead on each render. All internal and
external call sites updated to use [:> component* props] syntax.
