Note

Low Risk
Single UI formatting change limited to activity date header rendering; no data, auth, or business-logic impact.

Overview
Aligns Activity list date headers to always include the year by changing the formatDateWithYearContext fallback format from MMM d to MMM d, y in activity-v2.

This fixes inconsistent display when scrolling across year boundaries (current year vs previous years).
