Show registrar's official intent to graduate date in private student profile

[russtuck]

As a follow-on to the public (if a student chooses to set it) "planned graduation year", we could give students access to the registrar's official "intent to graduate" term. This is the field the registrar's office fills in when they process a senior's "intent to graduate" form.

The field is "Grad Flag" -- degree_history.udef_3a_2

• Empty means the student hasn't applied to graduate.
• The date is recorded in two parts: a letter (M, S, D) for the term and 2 digits for the year. The year is the calendar year, not the start of the academic year (unlike course codes) For example:
  • M23 means May 2023 (that is, Spring of the 2022-23 academic year)
  • S23 means summer 2023
  • D23 means December 2023

Note: It often takes a few weeks to process these forms, so there can be a several week delay between filling out the form and this field being updated. So if we show this field, we should also show a note explaining this so students aren't worried or impatient. There should also be a note saying students should not apply more than 12 months before they plan to graduate, but should apply soon after that, so if the registrar finds any forgotten requirements, there is time to adjust registration for the last 2 semesters to take care of it. The details should be checked with the Janet Potts in the registrar's office, and/or Alice Falcone the registrar.

(This issue of course will require both API and UI work, but issues must choose a single repo.)
