fix: use UTC datetime range for date filtering instead of UTC date comparison

- Calculate target_date_start_utc and target_date_end_utc for the target timezone's day
- Filter runs using >= and <= with UTC timestamps instead of date casting
- Fixes edge cases for timezones significantly offset from UTC (e.g., UTC+10, UTC-10)
- Prevents incorrect inclusion/exclusion of runs when local day spans UTC day boundary
