Reviewer's GuideRefactors DateTime parsing in DateTimePicker to use a new shared DateTimeHelper utility that supports more input formats and adds dedicated unit tests for the helper, improving robustness when parsing editable user input and supporting both DateTime and DateTimeOffset scenarios.

Hey - I've left some high level feedback:
- Switching
DateTimePicker.TryParseValueFromStringtoDateTimeHelper.TryToDateTimemeans theDateFormat/DateTimeFormatproperties are no longer used for parsing, which may change behavior for consumers relying on custom formats; consider allowing the helper to accept explicit format strings or preserving the previous format-based path where appropriate. - The
DateTimeHelpermethods accept non-nullablestringparameters but are tested and used with possible null values (e.g., vianull!in tests); updating the signatures tostring?and handling null explicitly at the API boundary would remove the need for suppressions and better reflect actual usage.

## Overall Comments
- Switching `DateTimePicker.TryParseValueFromString` to `DateTimeHelper.TryToDateTime` means the `DateFormat`/`DateTimeFormat` properties are no longer used for parsing, which may change behavior for consumers relying on custom formats; consider allowing the helper to accept explicit format strings or preserving the previous format-based path where appropriate.
- The `DateTimeHelper` methods accept non-nullable `string` parameters but are tested and used with possible null values (e.g., via `null!` in tests); updating the signatures to `string?` and handling null explicitly at the API boundary would remove the need for suppressions and better reflect actual usage.Help me be more useful!
