Forms: Display URL field values as clickable links in submission page (#46593)

* Forms: Display URL field values as clickable links in submission page

Add get_url_value_as_link() method to render URL field values as clickable
anchor tags in the form submission confirmation page.

- Check for 'url' field type in get_render_web_value()
- Validate URLs with esc_url() allowing only http/https protocols
- Links open in new tab with rel="noopener noreferrer" for security
- Invalid URLs are displayed as plain escaped text

* Minor code format change

* Fix Phan return type for get_render_web_value()

Update PHPDoc return type to string|array since URL fields now return
an array structure.

* Fix E2E test: only populate URL anchor text when URL exists

The anchor element now only gets text content when there's actually a URL,
preventing duplicate text elements that cause Playwright's getByText to
match multiple elements.

* Fix URL field rendering in submission confirmation

- Revert the && condition in data-wp-text that broke URL rendering
  (Interactivity API doesn't support && operator in expressions)
- Fix E2E test to use :visible selector to avoid matching both
  hidden .field-value and visible .field-url elements

* Preserve original URL input for display text

Add 'displayValue' field to URL field rendering to explicitly preserve
the user's original input (e.g., 'google.com') for display text, while
'url' is used for href and may have https:// prepended.

This ensures the link text shows what the user typed, not the normalized URL.
