Subject: [PATCH] agent_ui: Fix thread history item showing GMT time instead of
 local time on Windows (#42198)

Closes #42178
Now it's consistent with the DateAndTime path which already does
timezone conversion.

- **Future Work**
Happy to tackle the TODO in `time_format.rs` about implementing native
Windows APIs for proper localized formatting (similar to macOS's
`CFDateFormatter`) as a follow-up.

Release Notes:

- agent: Fixed the thread history item timestamp, which was being shown
in GMT instead of in the user's local timezone on Windows.
