[Payments] No longer show payments disbursed to a third party

[iandonovan]

Summary

• This work is behind a feature toggle (flipper): YES, there are two of them.

1. payment_history_exclude_third_party_disbursements, when enabled, ensures a user looking at Payment History will only see payments that were disbursed to them.
2. payment_history_recategorize_hardship, when abled, will recategorize some payments currently marked as Hardship as Chapter 33 Hardship instead.

Testing done

• New code is covered by unit tests
• Prior to this, a user looking at Payment History would see payments that were disbursed to others, like their dependents. This could introduce confusion if they interpreted the information as, e.g., seeing a payment on the page that they hadn't received.
• The recategorization is a separate issue. I am not entirely sure this change will be necessary if we are only showing payments disbursed to the user viewing the page, but we'll see.

What areas of the site does it impact?

• This is entirely confined within Payment History.
