feat: add RFC 9537 redaction support, vCard address/fax parsing, and registrar address fields

- Parse the top-level RDAP `redacted` array (RFC 9537) into a new `redactions` field on `DomainRecord`; set `privacyEnabled` when any redaction references "registrant"
- Expose `street`, `city`, `state`, `postalCode`, `country`, and `countryCode` on both `RegistrarInfo` and `Contact`; extract ISO 3166-1 alpha-2 from the vCard `cc` parameter (RFC 8605)
- Split `tel` entries by fax type parameter (`"fax"` / `["work","fax"]`) into separate `tel` and `fax` lists; collect multiple email addresses as an array, collapsing singletons to a plain string
- Prefer an exact `registration` event match over `reregistration` when extracting `creationDate` (RFC 9083)
- Merge `redacted` arrays in `mergeRdapDocs`, deduplicating by JSON identity
- Split `adr` street on `\r?\n` only (not commas) to avoid splitting inline comma-separated addresses
