fix: normalize DateTimeOffset to UTC in DashboardService to fix Npgsql offset rejection

Browse Source 
DashboardService was constructing 'today in Beijing' bounds with a +08:00 offset, which Npgsql rejects when binding to a timestamp with time zone column. Added .ToUniversalTime() to normalize to UTC (same instant, offset 0), matching the existing pattern in SessionAnalyticsService.GetUtcWindow.
