Remove prospect_id and adjust prompt table SQL

Remove the prospect_id foreign key from the prompt CREATE TABLE SQL and adjust column order (model moved before data). Also delete drop_llm_table.sql which contained DROP TABLE IF EXISTS llm. Note: this updates the table creation script only—apply a DB migration if you need to remove the existing column or preserve data.
