Sundar 🔥 empty response from leaderboard data api

[sundarmachani]

Description

Fixes a production issue where the Dashboard Leaderboard was displaying only the logged-in user instead of all eligible members.

The root cause was a runtime error in getLeaderboard() due to unsafe access of weeklySummaries[0].summary when weeklySummaries was empty or contained null values. This caused the function to throw internally, and because the error was being returned instead of thrown, the controller silently fell back to getUserLaborData(), which returns only the requesting user.

This fix ensures:
• Null-safe access of weeklySummaries
• Proper error propagation (no silent fallback)
• Consistent leaderboard behavior across dev and production environments
