feat: add optional activity header timestamps in chat settings

Add a new Chat checkbox to toggle timestamps for tool, reasoning, and justification headers (default off).
Keep assistant message footer timestamps visible and switch to a more readable compact date format.
Preserve hover timestamp overlays with chat-surface background when the new setting is enabled.
