	 * Whether author-configured outbound destinations from a form source should be honored.

	 * Destinations declared in the form content (webhooks, the legacy postToUrl attribute and
	 * the Salesforce integration) carry submission data to an outbound URL, so they are only
	 * honored when whoever placed the form had an administrator-level capability:
	 *
	 * - For post/page forms (`single`, numeric source id) the source post's author must have
	 *   the `manage_options` capability. Editor/Author/Contributor-authored forms are dropped.
	 * - For block templates, block template parts and widgets the source id is not a numeric
	 *   post, so there is no author to check. Editing any of those surfaces already requires
	 *   the `edit_theme_options` capability — administrator-tier, strictly above the
	 *   capabilities an Editor/Author/Contributor holds — so their destinations are trusted.
	 *
	 * The source type is established server-side (from the signed JWT, or by re-rendering the
	 * real template/template part on the legacy path) and is not forgeable by the submitter.
	 *
	 * Returns false for any other unresolved source (non-numeric id of an unknown type, or a
	 * numeric id with no admin-capable author).
	 *
	 * @param int|string $source_id   The form source id: a post id for post/page forms, or a
	 *                                non-numeric value for widget or block-template sources.
	 * @param string     $source_type The form source type: single, widget, block_template or
