fix(jira): handle JSON-stringified ADF in toAdf() for variable resolution

The executor's formatValueForBlock() JSON.stringify's object values when
resolving <Block.output> references. This means an ADF object from an
upstream Agent block arrives at the route as a JSON string. toAdf() now
detects JSON strings containing valid ADF documents or nodes and parses
them back, ensuring rich formatting is preserved through the pipeline.
