Issues fixed:
1. Charts not rendering correctly due to sparse data (missing time buckets)
2. Period "1h" returning empty data when aggregate stats not yet available
Changes:
- Generate continuous time series with 0 values for all time buckets
- Truncate start time to hour/day boundaries for consistent bucketing
- Fallback to package-level stats aggregation when registry totals unavailable
- Add proper time range filtering (since <= time_bucket <= now)
Behavior now:
- All time periods (1h, 1day, 7day, 30day) return complete data sets
- Missing hours/days are filled with value: 0
- Chart libraries can render continuous lines/bars correctly
- No more empty data for "1h" period
Example output (1 hour period):
Before: [{"timestamp":"14:00","value":5}, {"timestamp":"15:00","value":3}]
After: [{"timestamp":"13:00","value":0}, {"timestamp":"14:00","value":5},
{"timestamp":"15:00","value":3}, {"timestamp":"16:00","value":0}]
Resolves: "Chart doesn't generate correctly - it should automatically
fill 0 for the empty periods to render correctly"
