Add the ability to filter by processing period to the View Orders page

@Paweł Albecki thanks, I just tested this in test.openlmis.org and it works as expected.
FYI @Brandon Bowersox-Johnson

@Paweł Gesek @Sam Im @Brandon Bowersox-Johnson the problem was not with too small numbers of edge cases. Test case was wrote wrong because I wrongly understood ticket description. Apologies. I fixed wrong steps and added four additional steps.

@Paweł Albecki can you update the test case?

@Nikodem Graczewski @Paweł Gesek @Łukasz Lewczyński
The label for the filter is correct (Processing Period Start and Processing Period End). The test case needs to be updated to add testing for the cases when a user only selects a processing period end or only selects a processing period start date, and their expected results.

@Nikodem Graczewski @Paweł Gesek Team ILL had a group conversation about this and realized the AC was not 100% clear and the coding was not 100% in alignment.

@Sam Im is talking with @Mary Jo Kochendorfer today to iron this out. There may be a small label change, and a tweak to the Zephyr to catch more edge cases. With a quick code fix and re-testing, we believe it can move back to Done soon.
