What happened?
`frontend/src/pages/Memories/Memories.tsx` returns an empty fragment, while routing uses the real `MemoriesPage` from components.
Page-level tests import the page wrapper, so they can pass without rendering the real Memories UI.

This creates misleading route/page coverage and inconsistent page-layer structure.

Expected behavior:
- `pages/Memories/Memories.tsx` should render `MemoriesPage`
- route and tests should use the same page entrypoint
