fix(playwright): stabilise Entity.spec.ts deny-access tests against CI timeout flakiness (#29560)

The deny-access tests that use the `dataConsumerPage` fixture were
missing `test.slow(true)`, causing them to flake under CI load. The
fixture's fresh login plus `visitEntityPage`'s search-response wait
together routinely exceeded the 60 s test timeout when multiple entity
suites ran in parallel, producing an opaque "Target page, context or
browser has been closed" error at entity.ts:77.

- Added `test.slow(true)` (180 s budget) to the two affected tests:
  `User should be denied access to edit description` (all 16 entities)
  and `Data Consumer should be denied access to queries/sample data`
  (Table entity).
- Added `{ timeout: 30000 }` to `page.waitForResponse` in
  `visitEntityPage` so future failures produce a clear timeout error
  instead of the opaque page-closed message.
