fix(attio): gate remaining unscoped param mappings + comment-target back-compat

- taskFilterCompleted (list_tasks filter) was mapped to isCompleted for
  every operation; gate it to list_tasks so it can't override the
  isCompleted value on an unrelated update_task call
- Generic threadId (get_thread) was unconditionally forwarded and
  create_comment prioritizes thread_id first, so a leftover threadId
  from configuring get_thread could silently hijack a comment meant for
  a list entry or record; gate it to get_thread
- Default commentTarget to the pre-existing behavior (entry, or thread
  if commentThreadId is set) when absent, so blocks saved before this
  field existed keep working instead of throwing
