fix(calendar): prevent rejection of input entry when date is within min/max range

[kaylaa0]

Defect Fixes

• fix Calendar: Manual entry not possible if the entered date is the same as min date. #8304

Issue

• When a date is entered manually into the input field, it is rejected and the field clears itself, even though the same date can be selected via the picker and is within the valid range.
• This occurs because the time portion of the date (hour, minutes, seconds, milliseconds) is validated, even though it is neither visible nor relevant in this context.

Solution

• Adjusted the validation logic for manually entered dates.

Result / Test Cases

• Verified that manually entering the minimum date into the input field is now accepted.
• Verified that manual entries at both min and max dates are allowed as expected.

All above scenarios have been tested and work correctly.
