fix(Daterange): accessibility fix for daterange picker

[ssherigar-c-eightfold]

SUMMARY:

Issue

• The input field is always cleared when you move on with the TAB key
• The focus is not moving to the action items of the datepicker on Tab
• When opening the date field to type the date, it never registers the first number. It only opens the date picker

CHANGE TYPE:

• Bugfix Pull Request
• Feature Pull Request

TEST COVERAGE:

• Tests for this change already exist
• I have added unittests for this change

TEST PLAN:

• When the DatePicker is closed, pressing any character key opens it and the typed character appears in the input. Space and Enter also work correctly
• In RangePicker, after selecting a date or pressing Escape, focus returns to the correct input (start or end).
• After selecting the start date, focus correctly moves to the end panel/input, and after selecting the end date, the picker closes properly
• Focus remains inside the picker when trapFocus is enabled
• Input should not be cleared on Tab
