fix pyright errors surfaced by pre-commit

- `page.context.cookies()` returns Playwright's TypedDict ``Cookie``
  where `name` is not required; switch to ``cookie_info.get("name", "")``.
- In `test_linked_state.tab_factory`, the inner ``factory`` closure
  lost the ``linked_state.frontend_url is not None`` narrowing; capture
  the URL in a local variable before defining the closure so pyright
  keeps the non-None type.
