Add useUrlTableState (search, sort, page, page size and filter_<column>
in the query string via one nuqs useQueryStates call, with keyPrefix and
urlKeys for routes that host two tables or need legacy key names) and
useUrlTab (validated ?tab= param with a role-aware fallback). Migrate
the Virtual Keys table onto useUrlTableState with a byte-identical URL
contract and bind the Playground tab strip to ?tab=.
DataTable gains controlled columnVisibility/onColumnVisibilityChange
plus usePersistedColumnVisibility (localStorage per table id), and an
isError prop that keeps the server page clamp from rewriting a
deep-linked ?page= after a failed fetch. Virtual Keys uses both.
The expired-session redirect in handleError now keeps the query string
and hash so the return URL captured on re-login restores the filtered
view instead of the bare list.
Delete useTabRouting and tabRoutes, the pathname tab router left over
from the reverted path-per-tab attempt (#34327, reverted in #34629);
tab persistence has to be a query param on the static export.
