Fix OnlineBoardSearchPage tests for PageLayout restructuring

Tests failed because PageTabs uses Link from @modern-js/runtime/router
which wasn't included in the router mock. Added Link to the router mock,
added mocks for PageTabs, OnlineBoardFilter, and other transitive deps,
and updated error text assertions to match the new Russian strings.
