Pre-calculate and store polygon areas for faster API responses

[dancingsushii]

Description

This feature aims to improve API response times by pre-calculating and storing the area of each polygon during the data insertion process. By having the area available in square meters, the API can quickly retrieve this information without recalculating, thus speeding up response times for client requests that require area data.

Acceptance criteria

• Modify the data insertion process to calculate the area of each polygon in square meters and store this value in the database.
• Ensure that the area calculation is accurate and uses the correct geographic projections to provide reliable data.
• Update the API to fetch the pre-calculated area from the database instead of recalculating it during each request.
