refactor: convert utilities projects to follow procedural guidelines

[mrdeyroy]

Description

This PR refactors all Python CLI scripts in the utilities/ directory to adhere to the project's strict procedural guidelines (no functions or classes, emoji-based CLI output, robust input validation, and replay loops).

Fixes :

#804

Changes Made

• F1 Performance Analyzer: Removed functions (fetch_f1_data, display_standings, display_constructors, main) and inlined sequential logic. Swapped external requests dependency for standard urllib.request to comply with the "No External Dependencies" rule. Wrapped in a while True: loop.
• Number System Converter: Removed all helper conversion functions and inlined the logic directly in choice blocks. Wrapped in a while True: loop.
• Tower of Hanoi: Converted helper rendering/movement functions to procedural inlined logic inside a stack-based solver and replay loop.
• Typing Speed Tester: Converted logic to be purely procedural, inlining the random phrase API calls (with offline list fallbacks) and wrapping it in a replay loop.
• Tests Update: Rewrote tests/test_number_system_converter.py to use unittest and test the CLI interactions using subprocess.Popen to ensure full test coverage for the procedural implementation.

Verification Results

All 125 tests executed and passed successfully:

python -m unittest discover -s tests -v
