Root Cause

• In the frontend code (wren-ui/src/utils/time.ts), time formatting utilities like getCompactTime call dayJs(time) directly.
• When called with a numeric string (e.g., "1764725636199"), dayjs parses it as a date string rather than a millisecond timestamp, resulting in a completely wrong historical date.
• This affects all usages across the frontend that pass API response timestamps directly into these utilities without normalization.
