Fix test configuration for immediate_hydration default change

- Set immediate_hydration: true in test setup to match test expectations
- Update test expectations to use data-immediate-hydration attribute
- Add proper before/after hooks to manage test configuration
- Reduces test failures from 10 to 2 (remaining failures unrelated to immediate_hydration)
