Fix ride model technical specs

Implement plan to fix ride model technical specifications pipeline. This includes creating a new migration for the `ride_model_submission_technical_specifications` table, updating `entitySubmissionHelpers.ts` to handle insertion of technical specifications, and modifying the edge function `process-selective-approval/index.ts` to fetch these specifications. This ensures no data loss for ride model technical specifications.
