chore: Clean up repository and expand LocalGov Drupal walkthrough

Cleanup:
- Remove legacy sample-content directory (replaced by AI generator)
- Remove redundant .gitkeep files from directories with content
- Add cdk.context.json to .gitignore (account-specific cache)
- Update Dockerfile to remove sample-content COPY
- Remove import_sample_content() from init-drupal.sh

LocalGov Drupal walkthrough:
- Add steps 6-8 for Text-to-Speech, cleanup, and evidence collection
- Add TTS block configuration to init-drupal.sh
- Add optional block config for Listen to Page feature
- Add walkthrough screenshots for AWS console and Drupal UI
- Update step content and navigation
- Rename phase-config.yaml to phaseConfig.yaml

Dependency updates:
- Update yarn.lock with current dependencies
