"Class Block" Option for Permanent Class Opening Posts

Small but handy update live for Permanent Class Openings!
You can now post openings for a block of classes
 — not just single class times. When creating a Permanent Class Opening, there's a new toggle to switch between 'Single class' and 'Block of classes'. From there, you set a block name (optional), location, start/end times, and a start date. Instructors accept the whole block, which means less back-and-forth for recurring or grouped slots.
All other Permanent Class Opening behavior stays exactly the same
