Remove old schema fields from example configs and workflow

Updates all example config files and deployment workflow to use the new
simplified DNS/SSL schema.

Config Files Updated:
- ci-test.example.yaml: Removed app_name, pattern, custom_subdomain, create_zone, staging
- dev.example.yaml: Removed app_name, pattern, custom_subdomain, create_zone, staging
- example.config.yaml: Removed app_name, pattern, custom_subdomain, create_zone, staging
- prod.example.yaml: Removed app_name, pattern, custom_subdomain, create_zone, staging

All configs now use:
- dns.domain: Full domain name directly (no pattern construction)
- ssl.certificate_arn: For ACM support
- No ssl.staging: Let's Encrypt always uses production

Workflow Updated:
- terraform-deploy.yml: Removed pattern and custom_subdomain extraction
- Now only displays full domain when DNS enabled
