fix(journeys-admin): hide Load More button when no more images to load [NES-1692]

[edmonday]

Summary

In the media library, the "Load More" button used to stay visible after the last page and switch its label to "No more to load". That's confusing — feedback from Lyuba. Now the button is simply hidden when there are no more images to load.

Changes

• LoadMoreButton returns null when !hasMore && !loading (loading still shows the loading state).
• Drops the "No more to load" copy entirely.
• Updates LoadMoreButton.spec.tsx and MediaLibrary.spec.tsx to assert the hidden state.

Linear

• NES-1692

Test plan

• npx jest --config apps/journeys-admin/jest.config.ts --no-coverage on LoadMoreButton.spec.tsx and MediaLibrary.spec.tsx — 20 passed
• Manual QA: open media library drawer with a short result set and confirm the button disappears at the end
