v8.2.1: Refactor JS and Python models, remove unused functions, and improve form validation

Updated JavaScript to refine option selection logic and remove redundant functions (`showCompare`, `showCompareConfigs`). Enhanced Python models with validators to enforce non-empty inputs for critical fields (`port`, `maxconn`, etc.). Optimized configuration diff logic for better performance and readability. Added file lock checks before database migrations.
