feat: Add all remaining monitor options to group defaults

Support defaulting any monitor option at group level:
- expected_content, body (HTTP/HTTPS)
- ping_count (ICMP)
- dns_server, record_type (DNS)
- graphql_query, graphql_variables (GraphQL)
- db_type (Database)

Only name, type, target, link, reset_on_next_check, expected_ips,
and expected_cname remain monitor-specific (not defaultable).
