chore(algebra/order/{module, smul}): Move to the correct spot (#16131) Make algebra.order.module do what it says on the tin. Namely, move everything that wasn't about module to algebra.order.smul and generalize accordingly. As a bonus, add a shortcut instance for ordered_smul 𝕜 (ι → 𝕜) as this solves #16021.
