Fix session variable pollution

Browse Source 
Implement all phases to fix session variable pollution by changing `is_local` to `true` in the `create_submission_with_items` database function and the `process-selective-approval` edge function. This ensures session variables are transaction-scoped, preventing data corruption and attribution errors. Includes database migration, edge function updates, and monitoring for attribution mismatches.
