Fix CI test matrix failures caused by Ruff errors in app.py

[Copilot]

The Python 3.10–3.13 CI test jobs were all failing at the Ruff step before tests could run. The failure was isolated to app.py, where import hygiene and file formatting no longer matched the repository’s enforced lint rules.

• CI failure source

  • Removed an unused numpy import from app.py
  • Kept the import block aligned with Ruff’s ordering rules

• Formatting cleanup

  • Applied Ruff formatting to app.py so the file conforms to the repo’s enforced style checks
  • No functional behavior changes were introduced

Pull request overview

This PR resolves CI failures in the Python 3.10–3.13 test matrix by bringing app.py back into compliance with the repository’s enforced Ruff linting/formatting rules (import hygiene + formatting), without changing runtime behavior.

Changes:

• Removed an unused numpy import that was failing Ruff (F401).
• Applied Ruff formatting updates (quote style, blank lines, call formatting) to match repo style checks.
