Refactor: Add microtask yields to journals module for consistency

Added await Promise.resolve() yields after IndexedDB writes to ensure
Dexie observers fire before function returns. Aligns with pattern
established in event loaders fix.

Journals module was already working correctly (preserved try_cache),
but adding yields ensures consistent timing behavior across all
nested data loading patterns.
