fix(e2e): update resize tests for new autoResize semantics

- Add explicit height (400px) to Auto Resize test container
  (autoResize now requires container dimensions)
- Update test descriptions to reflect 0px chart in unconstrained containers
- Update infinite growth test doc to describe new expected behavior
