Add portfolio module styles, data export script, and initial JSON data

- Created a new CSS file for the portfolio module with minimal styling for various sections including KPI cards, property cards, and booking tables.
- Implemented a Python script to export property operations data from the Day 09 database to a JSON format for visualization in the portfolio module.
- Generated initial JSON data for the portfolio overview, revenue by day, occupancy by day, and detailed property performance metrics.
