Database stores times in UTC but serialized without timezone info, causing frontend to misinterpret as local time. Now all datetime fields include 'Z' suffix to indicate UTC, enabling proper timezone conversion in the browser. - Add UTCDatetimeBaseModel base class for Pydantic schemas - Update model to_dict() methods to append 'Z' suffix - Affects: tasks, users, sessions, audit logs, translations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
