Upgrade uv.lock

[nitbharambe]

Lock file contains a version for fonttools 4.59.2 which is flagged as a vulnerability. GHSA-768j-98cg-p3fv

• Added a seed to all random (Only used at assignments of PF and SE)
• Reran all notebooks (except SE assignment solutions)

Also not sure if there is a easy + direct solution via dependabot. Check dependabot/dependabot-core#11913

Re-ran all notebooks since a lock file is expected to work unconditionally when upgraded. (State estimation assignment gets changes which are resolved in #28 . We should merge that PR.)

The changes here should only clear out metadata.

A handy script for automating notebook runs:

find ./examples -name "*.ipynb" -not -path "*/.ipynb_checkpoints/*" | while read notebook; do
  echo "Processing: $notebook"
  uv run jupyter nbconvert --to notebook --execute \
    --inplace \
    --ExecutePreprocessor.timeout=600 \
    --ClearOutputPreprocessor.enabled=True \
    --ClearMetadataPreprocessor.enabled=True \
    "$notebook" || echo "Failed to process $notebook"
done

If needed we can include as an action and/or pre-commit at this repository and/or other repositories,
