refactor: remove unused remarks and add quick domain create

Drop remark fields from Zone, Zone domains, proxy routes, WAF rule
groups and IP groups across models, APIs, UI and DB columns (keep
certificate/origin remarks). Add quick-create domain input for short
labels, @ apex and full FQDNs when binding domains.
