fix(datadog): Encode metadata error value before embedding in error field

format_error/4 embedded the raw metadata :error value into the log line,
bypassing RedactorEncoder. A non-JSON-encodable term (e.g. an {:error,
reason} tuple) then crashed the encoder, and because maybe_merge is
left-biased the encoded copy of the metadata could not overwrite it. The
formatter crash surfaces as "FORMATTER CRASH: ..." fallback lines and the
original log event is lost entirely.

Run the value through encode/2 (which also applies redactors), matching
how every other part of the line is built.
