## What kind of change does this PR introduce?
Component update.
## What is the current behaviour?
TanStack tables in the repo are split between the shared `TableHeadSort`
primitive and the older Studio-local `DataTableColumnHeader` helper,
which makes the sorting UI and integration path inconsistent.
If you were to just use `DataTableColumnHeader` in `ui-patterns/Table`,
you’d get a very different visual result to the `TableHeadSort` UI you
see in most other tables.
## What is the new behaviour?
Adds a shared `TanStackTableHeadSort` adapter in `ui-patterns/Table`,
backed by the existing `TableHeadSort` primitive, and switches the
webhook table plus the design-system TanStack demo to that canonical
path. `DataTableColumnHeader` stays as a deprecated wrapper for now,
Studio gets a lint guard to block new imports of it, and the table docs
now point TanStack tables at the shared adapter explicitly.
## To test
Check out column sorting on the Platform Webhook endpoint deliveries
table.

The changes required for this React Doctor need more thought that I can
hammer with AI. Just need to stop this from happening in the future with
