Add index on (blob_id, project_id) to BufferZone table to optimize: - JOIN queries between BufferZone and GeneralBlob - CASCADE DELETE performance when GeneralBlob records are deleted Without this index, cascade deletes would cause full table scans.

Problem
The
buffer_zonestable has a foreign key constraint on(blob_id, project_id)referencinggeneral_blobs, but there's no index on these columns.This causes:
general_blobsrecords are deletedBufferZoneandGeneralBlobSolution
Add index
idx_buffer_zones_blob_id_project_idon(blob_id, project_id)columns.Migration
After deploying, run the following SQL to add the index to existing databases:
CREATE INDEX idx_buffer_zones_blob_id_project_id
ON buffer_zones (blob_id, project_id);## Testing
