LOG-8090: escape 'new line' (\n) in EventRouter message

[vparfonov]

Description

This PR addresses a issue where Syslog output format corruption occurs if log messages generated by the Eventrouter contain newline characters (\n), this leads to malformed syslog data.
This fix ensures that the log message payload is properly escaped, preventing the introduction of malformed lines.

When JSON contains \n that becomes a real newline after decoding; sending real newlines in syslog breaks framing and creates split events. This change escapes newline characters (\n) in message payloads so the syslog sink emits a single safe line.
