feat(journals): implement centralized export templates and bulk interop

- Added 'ae_journals_export_templates.ts' with Markdown, HTML, and JSON support
- Refactored 'ae_comp__modal_journal_export.svelte' to use the new template system
- Optimized bulk export with automated template selection based on Journal type
- Integrated 'Import Entries' action directly into the Journal menu
- Updated project documentation to reflect portability features and implementation status
