SDPR API - Return SINS

[CarlyCotton]

User Story
As another ministry group, I need to know about any students who may have a full-time application in a given date range. These SINs will be matched against our client list, with any matches then being requested via the existing API to get application specific data.

Acceptance Criteria

• New external API that can return all SINs (legacy and SIMS) that meet specific criteria:
  • A FT application with a start date between now and 90 days in the future consider only current assessments (no cancelled apps but any other status).
  • An application within a study period consider only current assessments (no cancelled apps but any other status).
  • FT Disbursements sent in the last 90 days. For legacy, use sfas_application_disbursements.date_issued
• Same route as existing SDPR API
• For SIMS data, use only the most recent validated SIN

Additional Context
This is replacing the current process in legacy that is done via flat file transfer. SDPR sends a monthly file with a list of their client information and we send back all current applications for any students with a matching SIN.
The new process reduces volume of personal information shared between groups. Volume of SABC SINs that meet the criteria listed above is smaller than the list of SDPR clients currently being sent.

Update the ACs to clarify FT applications/disbursements and to change the range in disbursements from the last 60 days to the last 90 days.
