fix(tool-input): correct workflow selector visibility and tighten (optional) spacing

- Set workflowId param to user-only in workflow_executor tool config
  so "Select Workflow" no longer shows "(optional)" indicator
- Tighten (optional) label spacing with -ml-[3px] to counteract
  parent Label's gap-[6px], making it feel inline with the label text
