Refactor TextField and TextField-based component styling

BREAKING CHANGE: The DateField component has been redesigned with several key updates:

• The calendar icon has been repositioned to the end of the input field, and the chevron icon has been removed.
• The hasAdornments prop has been deprecated and replaced by a new prop, showCalendarButton, which controls the display of the calendar icon. This new prop defaults to false, maintaining the current behavior unless explicitly enabled.
• Moved TravellerField to deprecated Storybook folder.

TextField Design Consistency: Fixed design inconsistencies in the TextField component according to the specifications in the Figma file.

Refactored Styling for TextField-Based Components: Updated styling for all TextField-based components—Select, Autocomplete, Stationpicker, DateField, DatePicker, TravellerField, and FormField—to enhance code maintainability and streamline future modifications.
