feat(journals): extract decryption logic to helper and improve Quick Add behavior

- Extracted journal entry decryption workflow to 'ae_journals_decryption.ts' to decouple it from Svelte reactivity and address loop issues.
- Updated 'ae_comp__journal_entry_obj_id_view.svelte' to use the new decryption helper.
- Refactored 'Quick Add' to use the first line as the title and remove it from the content before saving.
