Migrate all tables to TanStack from AG Grid

[RichDom2185]

Following #2437, we now have two different dependencies used for tables.

This causes a lot of unnecessary bloat in our JS bundle.

Ideally, we should use only one library for all our table needs.

Let us migrate away from AG Grid to TanStack table as it it a more popular (and newer) library.

After #2893 merges, Grading would have been migrated, but Team Formation will become an issue for this thread as they copied the previous grading table code before Grading's migration. I've left badges in GradingBadges to support the legacy colours the old table used, but if anyone migrates that table, please do remove that legacy function, thank you!
