style(journals): apply expanded 80-width formatting and snake_case

- Batch formatted all Journals module files using Prettier with printWidth: 80.
- Refactored preventDefault to prevent_default across all Svelte components.
- Standardized line breaks for imports and long attribute lists for better readability.
- Ensured consistent snake_case naming for internal identifiers.
