fix duplicated enhanced tab & streaming UI enhancement (#1882)

* feat(enhanced-notes): normalize template id comparisons and

include finalizing session mode
- Use `templateId || undefined` instead of `templateId ?? undefined`
  to coerce empty-string values to undefined so template id 
  normalization treats empty strings the same as missing values.
  Normalize existing template id value (`existingTemplateId || 
  undefined`) before comparison to avoid false mismatches when stored 
  values are empty strings.
  Treat "finalizing" sessionMode as a running state that short-circuits
  enhanced-note processing, preventing modification during finalization.
  ese changes fix incorrect equality checks and ensure enhanced note
logic behaves correctly for empty template ids and during finalization.

* streaming ui
