fix: resolve PostgreSQL migration issues for development environment

- Added DATABASE_CLIENT=pg to docker-compose.dev.yml for PostgreSQL connection
- Fixed migration 032 to check if tables exist before creating
- Removed language-specific email template columns (use standard columns)
- Added conditional checks for app_settings and email_templates inserts
- Created helper scripts for migration state management
- Added .env.dev with PostgreSQL configuration for development
