A new Time format setting in /config controls whether UI clocks use 12-hour, 24-hour, UTC or a custom pattern.

A new timeFormat setting is available in /config under "Time format," controlling the clock format used for times shown in the UI. Options are auto (default, follows the locale), 12-hour, 24-hour, 24-hour-utc (e.g. 18:05Z), or a strftime pattern. Changing it fires tengu_time_format_setting_changed telemetry.
