Subject: feat(v3.6.0): add iCloud sharing for workflows and tracked domains

- implement CloudKit sharing (CKShare) for TrackedDomain and DomainWorkflow
- support read-only and editable permissions
- add Share actions and shared state indicators in UI
- handle shared record ownership and participant roles
- implement deterministic conflict resolution to prevent duplication
- ensure compatibility with existing iCloud sync layer
- maintain local-first behavior with graceful offline handling
- remove debug logging for domain availability/rdap messages

notes:
- no custom backend or accounts introduced
- sharing is Apple ecosystem only (iCloud-based)
- large history data remains local-only
