Member/Setting/validations: domain, actor, and seeds

- setting.ex: domain/authorize for default_membership_fee_type_id check
- validate_same_interval: require membership_fee_type (no None)
- set_membership_fee_start_date: domain/actor for fee type lookup
- Validations: domain/authorize for cross-resource checks
- helpers.ex, email_sync change, seeds.exs actor/authorize fixes
- Update related tests
