perf(hydration): resolve white page delay by removing blocking awaits from layouts

- Refactored Events root layout to fire load_ae_obj_id__event in the background.
- Refactored Journals list page to fire load_ae_obj_li__journal in the background.
- Combined with SWR module logic, this ensures near-instant UI rendering from Dexie cache while refreshes occur asynchronously.
