Add StatTiles and BadgesStrip widgets wired into ProgrammerDashboard.
StatTiles shows 2 tiles (focus + completed) when showSheetStats is false,
and 5 tiles (+ streak, first-pass approval, help given) when the viewing
user's role is programmer. BadgesStrip renders earned/locked chips in a
horizontal Wrap with tap-to-dialog detail.
Dashboard feeds todayFocus via buildDayRows/totalSeconds, leaveDays via
approvedLeaveDays, and sheets: const [] until Task 20 wires real data.
