{#
  AI Intent + AI Change Summary section — shared include for watch edit and tag/group edit.

  Required template context:
    llm_configured  — bool: LLM provider is configured in settings
    form            — the WTForms form (must have .llm_intent and .llm_change_summary fields)

  Group/tag edit only:
    llm_group_edit  — bool: True when rendering the tag/group edit page. This is the ONLY
                      way to tell the two contexts apart — the tags blueprint also passes
                      the tag dict as `watch`, so `watch` is truthy in both.
                      form.llm_backend_profile is ternary here (On / Off / Leave it to each
                      watch) and is the group's only AI control; on a watch it is a checkbox.

  Watch edit only:
    watch               — the Watch object (for processor check and prefilter display)
    llm_group_overrides — dict returned by _resolve_llm_group_overrides():
                          {'llm_intent': {'value': str, 'group_name': str} | None,
                           'llm_change_summary': {'value': str, 'group_name': str} | None,
                           'llm_backend_profile': {'value': bool, 'group_name': str} | None}
                          The two prompt entries are non-None only when the watch has no own
                          value AND a linked group set to "On" has one — that is what puts
                          "From group '<name>': <value>" in the placeholder.
                          llm_backend_profile is non-None when a linked group has taken the
                          on/off decision (On or Off, not "leave it to each watch") — #4204.
