Bug Fixes

1. SqlLogger syslog handling decoded VariableValue, not the underlying JSON string

   What was broken:

   • Syslog updates from SystemLogLast arrived as VariableValue, but the logger passed that wrapper to json.loads().

   Inputs that triggered it:

   • Any SystemLogLast update routed into SQL logging.

   Result:

   • Valid syslog entries failed to decode and log correctly.

   Fix:

   • Unwrapped the stored string payload before JSON decoding.
