🎨 Palette: Add progress bar for quiet mode

[EiJackGH]

💡 What: Added an interactive progress bar for long-running simulations when the --quiet flag is enabled in bitcoin_trading_simulation.py.

🎯 Why: Dense numerical data and long-running processes without output can make users feel like the program has frozen. Providing a progress bar gives immediate feedback on system status while preventing standard output log pollution, especially important for non-interactive environments where logs could be overwhelmed.

📸 Before/After: The --quiet flag previously produced no output until the final report. Now, when run interactively, it produces a dynamic progress bar that redraws itself on a single line.

♿ Accessibility: The progress bar is only rendered when sys.stdout.isatty() is True, ensuring that log files or non-interactive environments (e.g. CI/CD) are not polluted with \r carriage returns or garbage characters.
