RG-T131 Log time issue fix

[ucswift]

Summary by CodeRabbit

• Bug Fixes
  • Corrected log and call timestamps so entries are stored consistently in UTC based on the department’s local time zone.
  • Improved handling of ambiguous or skipped daylight-saving-time timestamps.
  • Preserved original timestamp values when time-zone information is unavailable or the value is unspecified.

Thanks for opening this, but we'd appreciate a little more information. Could you update it with more details?

Changes

The change adds optional lenient DST resolution to ConvertToUtc. User log timestamps are parsed in the department time zone and converted to UTC before persistence. Missing time-zone data and DateTime.MinValue preserve the existing value.

Timestamp normalization

Layer / File(s)	Summary
Configurable UTC conversion Core/Resgrid.Framework/DateTimeHelpers.cs	ConvertToUtc supports lenient time-zone resolution while keeping strict resolution as the default.
Log entry conversion Web/Resgrid.Web/Areas/User/Controllers/LogsController.cs	Run, work, meeting, coroner, and unit timeline timestamps use shared parsing and UTC conversion helpers. Conversion is skipped when department time-zone data is unavailable or the value is DateTime.MinValue.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 9d928

The time-conversion change is merge-ready after normal checks and review; no actionable merge-blocking risk remains.

Add DST transition tests for both resolution modes.

No existing tests cover ConvertToUtc. Test skipped and ambiguous local times with lenient: true, and assert SkippedTimeException and AmbiguousTimeException with lenient: false.
