Fix production SAV module issues by adding missing columns and updating schemas

Introduce a SQL migration script to address critical production issues in the SAV module by adding missing columns to the `sav_tickets` table, correcting default values, and ensuring proper foreign key constraints and indexes are in place. This resolves "column does not exist" errors and aligns the production database schema with the development environment.
