+/**
+ * Centralizes the anti-double-submit + anti-deadlock logic shared by the
+ * "add/edit" modals.
+ *
+ * The lock has to straddle antd's async field validation, whose result comes
+ * back through two separate callbacks (`onFinish` / `onFinishFailed`). So the
+ * three wiring points below are intentional and map 1:1 to those anchors:
+ *
+ * - `guard`   wrap the submit trigger (button / ModalFooter onOk). Blocks
+ *             re-entry while a submit is already in flight, then fires submit.
+ * - `run`     wrap the `onFinish` handler. Holds the lock + loading until the
+ *             `onOk` request settles (success or error).
+ * - `release` pass as the form's `onFinishFailed`. Releases the lock when
+ *             validation fails, otherwise the button would dead-lock.
