fix(analytics): show per-student last seen from login and session activity (#674)

* fix(analytics): show per-student last seen from login and session activity

Return ISO last-seen timestamps from course analytics instead of
pre-formatted strings so the dashboard can format them per student.
Batch-fetch last seen for all students and include session activity
alongside login events for more accurate, distinct values.

* fix(analytics): destructure first row from getLastLogin query results

Promise.all returns an array per Drizzle select; nested destructuring
is required so loggedInAt and updatedAt are read from row objects.
