What?

• Closes Dates misalignment in the Date filter in DataViews #72655
• This PR changes the date input controls in the Dataviews component from native type="date" inputs to type="text" inputs with locale-aware formatting and placeholders.

Why?

Native type="date" inputs display dates in a browser-specific format (typically yyyy-mm-dd) . Users expect to see dates formatted according to their locale settings (e.g., dd/mm/yyyy in Europe, mm/dd/yyyy in the US). This change provides:

1. Locale-aware date display - Dates are now displayed in the user's preferred locale format
2. Better placeholder guidance - Input fields show locale-appropriate placeholders (e.g., dd/mm/yyyy or mm/dd/yyyy)
3. Consistent experience - Both single date picker and date range picker now share the same formatting logic

How?

Changes made:

1. dataviews-filters/utils.ts:

   • formatDateValue(value: string) - Formats an ISO date string (yyyy-mm-dd) to a locale-aware display string using toLocaleDateString()
   • getDatePlaceholder() - Generates a locale-aware placeholder string (e.g., dd/mm/yyyy, mm/dd/yyyy) using Intl.DateTimeFormat

2. dataform-controls/date.tsx:

   • Imported the new utility functions
   • Changed InputControl type from "date" to "text" for both single date and date range inputs
   • Added placeholder prop using getDatePlaceholder()
   • Applied formatDateValue() to display dates in the input value

3. dataviews-filters/filter.tsx:

   • Imported formatDateValue utility
   • Applied date formatting to filter label display for active date filters
   • Handles both single date values and date range arrays

Testing Instructions

1. Open the WordPress admin area with Gutenberg active.
2. Navigate to any view that uses Dataviews with date filters (e.g., Posts list with date filter).
3. Open a date filter and observe:
   • The date input fields should display a placeholder in your browser's locale format (e.g., dd/mm/yyyy for UK, mm/dd/yyyy for US).
   • Select a date using the calendar widget or type a date in the input.
   • The date should display in your locale format instead of yyyy-mm-dd.
4. Test with a date range filter:
   • Both "From" and "To" inputs should show locale-aware placeholders.
   • Selected dates should display in locale format.
5. Verify that filter chips/tags for date filters show the formatted date value.
