Adding new zoned timestamp feature type that stores both timestamp (int64) and zone info (str). If zone is UTC, it only stores timestamp. This is similar to ZonedDateTime in java. This proto type will map to datetime with zoneinfo to load for configured zone. For example,

now_la = datetime.now(ZoneInfo("America/Los_Angeles"))

If Codex has suggestions, it will comment; otherwise it will react with 👍.

Codex can also answer questions or update the PR. Try commenting "@codex address that feedback".

Address Codex review findings on PR feast-dev#6537:

- Serialize ZonedTimestamp as an ISO 8601 string in feature_server_utils
  and proto_json so JSONResponse can encode zoned-timestamp features
  (the raw protobuf message is not JSON-serializable).
- Reject ZonedTimestamp as an Array/Set base type, since there is no
  ZONED_TIMESTAMP_LIST/_SET ValueType for to_value_type() to resolve.
- Preserve fixed-offset zones (e.g. UTC-07:00) on decode instead of
  silently falling back to UTC and shifting the wall-clock time.
- Resolve 'ZONED_TIMESTAMP' (and 'SCALAR_MAP') in
  _convert_value_type_str_to_value_type so registry REST/codegen no
  longer render the type as String.
