/**
 * Normalizes a tooltip specification into `TooltipType` props.
 *
 * If the input is a string or React element, returns a basic tooltip config
 * with `placement: "top"` and the content set. If it's an object, merges
 * it with the base config (adding `ref` and `placement`).
 *
 * @param {TooltipType} tooltip - A tooltip string, React element, or full `TooltipType` config.
 * @param {RefObject<HTMLElement>} innerRef - Optional ref to attach to the tooltip's trigger element.
 * @returns A `TooltipType` config with `ref` and `placement` set, or `undefined` if tooltip is falsy.
 *
 * @example
 * ```tsx
 * getTooltipProps("Hello world");
 * // { ref, placement: "top", content: "Hello world" }
 * getTooltipProps({ content: "Tip", placement: "bottom" });
 * // { ref, placement: "bottom", content: "Tip" }
 * ```
