perf(hydration): optimize page loads and silence background fetch noise

- Implemented SWR pattern for Journal and Site Domain lookups.
- Refactored +layout.ts across modules to fire background refreshes instead of blocking.
- Updated +layout.svelte to render the layout shell immediately while hydrating.
- Silenced 'AbortError' and 'NetworkError' in api_get_object.ts and api_post_object.ts for log_lvl 0.
- Resolved duplicate export errors in ae_journals__journal.ts.
