Add numbering to course students

[JasonGrace2282]

• Explicitly order names by first name, in case of a last name conflict (EDIT: Removed from PR)
  • The way to sort stuff in cases of identical values is not in the SQL specification, so we can't rely on that sorting a specific way.
• Adds a counter to the names (see below)

@alanzhu0 that isn't necessary for Tin, since it uses a squash and merge workflow.

My only worry is that these two tables aren't the only ones that would benefit from numbering (as in, it's better to number every table of students than it is to just number two specific tables on a certain page). I'll take a look soon and let you know whether this is an actual change request or just a hallucination :)
