fix(chat): cache timer no longer stalls transcript rendering

The live CacheTimerBadge effect read the `current` state it wrote, so on a
real (advancing) clock it re-ran itself until Svelte threw
effect_update_depth_exceeded, aborting the reactive flush — turn data
rendered late. The effect now uses locals and never reads its own write.

Also: drop the timer icon (time only), and size step-line timers xs to
match the step cache badge (turn lines stay sm).
