Upgrade dependencies + upgrade Python version (#237)

## Ticket

## Changes
Upgraded python version from 3.12 to 3.13

Upgraded many package versions of other dependencies

## Context for reviewers
This should be uneventful, the upgrade from Python 3.12 -> 3.13 had very
little that would be breaking (many of the major changes need to be
enabled explicitly).

The package versions are just catching up on updates - we've been doing
a better job of this in the simpler grants repo. There are several
vulnerabilities this should fix.
