Add migrations to rename prospects columns

Add three SQL migration files and corresponding Python runner scripts under app/api/prospects/sql to rename columns on the prospects table. Renames: company_name -> company, primary_email_last_verified_at -> sell_by_date, and primary_email_source -> source. The Python scripts use app.utils.db.get_db_connection_direct to execute the ALTER TABLE statements and print a completion message.
