Overview

Undo / redo — RAILS.md §16.

POST /grids/:resource/undo   → revert the user's last mutation
POST /grids/:resource/redo   → re-apply the last undone mutation

Each replays the prior/new value through grid.apply_cell!, so it goes through the same save → validation → cascade → auto-broadcast path as a normal edit. Scoped per current_user + resource. Audits whose row has since been deleted are skipped (and marked) rather than failing the request.
