feat(tools): add fields parameter to Jira search block (#4091)

* 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.

* fix(tools): restore type annotation for implicit any in params callback

The params object is untyped, so TypeScript cannot infer the string
element type from .split() — the explicit annotation is required.
