Update station and campaign geometries after CSV upload

[mosoriob]

Description

When a CSV file is uploaded, we need to update the geometries for both stations and campaigns in the database. The database already has two functions to handle this: update_campaign_geometry and update_station_geometry.

Implementation Details

1. Current State:

   • CSV upload process exists but doesn't trigger geometry updates
   • Database functions update_campaign_geometry and update_station_geometry are available

2. Required Changes:

   • Add a post-processing step after CSV upload validation
   • Call the appropriate database functions to update geometries
   • Consider transaction handling to ensure data consistency

3. Technical Considerations:

   • Should both functions be called in sequence or in parallel?
   • Is there a dependency between campaign and station geometries?
   • Are there performance concerns with large CSV uploads?

Acceptance Criteria

• After a CSV is successfully uploaded, both station and campaign geometries are updated
• The process handles errors gracefully
• Updates are logged for monitoring purposes
• Performance remains acceptable with larger datasets
