Add Python installation detection and Windows-specific instructions

DEPLOY SCRIPT IMPROVEMENTS:

- Added explicit Python availability check before CSV generation

- Supports both python3 and python commands (Windows uses 'python')

- Clear error message if Python is not installed

- Windows-specific installation instructions with Microsoft Store option

- Linux/macOS instructions to run dependency installer

- Prevents silent failures when Python is missing

DEPENDENCY INSTALLER ENHANCEMENTS:

- Enhanced Windows section with detailed installation steps

- Added Microsoft Store option (easiest for Windows users)

- Added official Python installer option with PATH checkbox reminder

- Clear verification command: python --version

- Instructions to close/reopen PowerShell after installation

PROBLEM SOLVED:

- CSV import was showing 0 rows because Python script never ran

- Python not installed on Windows by default

- Script failed silently without clear error message

- Users now get clear instructions on how to install Python

NEXT STEPS FOR USERS:

1. Install Python 3 from Microsoft Store or python.org

2. Close and reopen PowerShell

3. Run ./deploy.sh again

4. CSV generation will work and data will persist
