fix(reader-dashboard): recentDocs items were always undefined for READ_ALL users

The server mapped DocumentSearchResult items as { document: Document }[]
but the API returns flat DocumentListItem[] — so i.document was always
undefined, crashing the reader homepage with a 500.

Fix the type + mapping in +page.server.ts, add createdAt/updatedAt to
DocumentListItem (needed by ReaderRecentDocs for relative-time display),
and update the component to accept DocumentListItem instead of Document.
