feat(tools): add fields parameter to Jira search block

Expose the Jira REST API `fields` parameter on the search operation,
allowing users to specify which fields to return per issue. This reduces
response payload size by 10-15x, preventing 10MB workflow state limit
errors for users with high ticket volume.
