fix: correct Created On date range filter behavior

Fix: "Created On" Between Date Filter Returns No Results (#3518)

Problem

The Created On filter does not work correctly when the Between operator is selected. Even when records exist within the selected date range, the ticket list incorrectly displays "No data available."

This issue occurs because the front-end does not consistently handle the value emitted by DateRangePicker when constructing the filter value.

Root Cause

DateRangePicker emits the selected date range as a string[] ([startDate, endDate]), while parts of the filtering logic expected a comma-separated string.

As a result:

• The Between filter value was not parsed consistently.
• Date range values were processed incorrectly before the filter was applied.
• An invalid filter value was generated, causing records that fall within the selected date range to be excluded from the results.

Solution

The date range handling has been updated to support both array and string inputs, ensuring the Between filter is parsed correctly regardless of the value format returned by DateRangePicker.

The implementation now:

• Accepts the string[] value emitted by DateRangePicker.
• Maintains compatibility with legacy comma-separated string values.
• Safely handles unexpected or empty inputs.
• Generates the correct filter value so records within the selected date range are returned as expected.

This restores the expected behavior for the Created On → Between filter while preserving compatibility with existing filter functionality.

Confidence Score: 5/5

Targeted two-file fix for a well-understood parsing mismatch; no side-effects on other filter operators.

Both changed functions now correctly branch on Array.isArray, the ' to ' delimiter detection covers the actual DateRangePicker output format, and legacy comma-separated paths are preserved. No regressions visible in adjacent logic.

No files require special attention.
