Fix Bug #503: fallback修复

* 为此在 {@link #dispenseOrder(Long, List<Long>)} 方法中重新组织代码顺序，并在异常捕获后抛出统一的 BusinessException。
|

*
|
||||
* 同时保留原有的业务日志记录，以便审计。
|
||||
*
|
||||
* 关键修复点（Bug #505）：
|
||||
* 在“医嘱校对”模块，护士仍能对已由药房发药的医嘱执行“退回”操作，导致业务不一致。
|
||||
* 退回（return）业务应仅在医嘱未发药（{@link DispenseStatus#NOT_DISPENSED}）或已撤销（{@link OrderStatus#CANCELLED}）的情况下允许。
|
||||
* 为此在 {@link #returnOrder(Long)} 方法中加入发药状态校验，若医嘱已发药则抛出 {@link BusinessException}，阻止后续退回流程。
