 * Renders a formatted timestamp, supporting compact and full display modes.

 * rules apply (today → time, yesterday/this week → day word + time, else date + time).
 *
 * @param {number} ts - The timestamp to display.
 * @param {boolean} [compact=false] - If true, always show only the time.
 * @param {boolean} hour24Clock - Whether to use 24-hour time format.
 * @param {string} dateFormatString - Format string for the date part.
 * @returns {React.ReactElement} A <Text as="time"> element with the formatted date/time.
