fix(seerr): use ensure_dependencies in update script

node-gyp's bundled node-gyp (v8.4.1) uses distutils which was removed
from Python 3.12+. Adding python3-setuptools provides the distutils
shim needed to compile native sqlite3 bindings.

Also adds build-essential + python3-setuptools before pnpm install in
the update function to match the install script's dependency setup.

Fixes #12939
