refactor: standardize 'prevent_default' helpers and batch format modules

- Renamed internal 'preventDefault' helpers to 'prevent_default' for project-wide snake_case consistency.
- Corrected native event method calls from 'prevent_default()' to 'preventDefault()' to resolve runtime TypeErrors.
- Applied batch formatting (printWidth: 80) to Journals and IDAA Recovery Meetings modules.
- Removed deprecated 'preventDefault' imports from svelte/legacy.
- Fixed Journal Entry 404 by migrating loader to V3 API helper.
