Fix Bug #495: 【医嘱闭环】已校对医嘱无法流转至"医嘱执行"界面，导致费用无法提交执行

Root cause: In getInpatientAdvicePage(), encounterIds and exeStatus were nullified
before buildQueryWrapper to prevent auto-generated SQL conditions, but requestStatus
was NOT nullified. HisQueryUtils.buildQueryWrapper uses reflection to add eq conditions
for ALL non-null fields, so requestStatus: 3 became an extra SQL filter
"AND request_status = 3" that was not intended for the 医嘱执行 page.

The 医嘱执行 page uses exeStatus (not requestStatus) for execution state filtering.
The SQL already handles verified/unverified order filtering via a CASE condition
on status_enum and performer_check_id. The requestStatus parameter is only meant
for frontend tab selection and should not be used as a SQL filter here.

Fix: Nullify requestStatus before buildQueryWrapper, same as encounterIds/exeStatus.
