enhancement(header): link site name to wp-admin

[faisalahammad]

Summary

The site name in the Press This header linked to the site front-end (home_url()) instead of wp-admin, leaving no quick way back to the dashboard. The header site name now opens wp-admin, and the link is filterable.

Resolves #4

Changes

class-wp-press-this-plugin.php

Before:

'siteUrl' => home_url( '/' ),

After:

$site_link_url = apply_filters( 'press_this_site_link_url', admin_url() );

$press_this_data = array(
	// ...
	'siteUrl' => home_url( '/' ),
	'adminUrl' => $site_link_url,

Why: Adds a new adminUrl key defaulting to the dashboard, with a press_this_site_link_url filter so the link target can be changed without overriding the data array. The existing siteUrl key is untouched, so the standalone-mode "View Site" menu item still points to the front-end.

src/App.js + src/components/Header.js

Before:

<a href={ siteUrl } target="_blank" rel="noopener noreferrer" className="press-this-header__site-link">

After:

<a href={ adminUrl || siteUrl } target="_blank" rel="noopener noreferrer" className="press-this-header__site-link">

Why: The site name link uses adminUrl with a siteUrl fallback for backward compatibility. App passes adminUrl={ data.adminUrl } through to the Header.

Also guarding html() so it returns instead of die() when PRESS_THIS_PHPUNIT is defined, which lets the existing test helper capture window.pressThisData. This fixed a broken JSON-extraction regex in two test helpers that never ran to completion before.

Testing

Test 1: Site name opens wp-admin

1. Open Press This (Tools → Press This, or bookmarklet)
2. Click the WordPress icon / site name in the header
3. Confirm a new tab opens …/wp-admin/ (dashboard)

Result: link points to wp-admin, not the front-end

Test 2: View Site still opens front-end

1. Open Press This in standalone mode
2. Open the header overflow menu (⋮)
3. Click View Site (only shown in standalone mode)

Result: opens the public front-end (home_url)

Test 3: Filter override (optional)

1. Add to a theme functions.php or mu-plugin:

   add_filter( 'press_this_site_link_url', function () {
       return home_url( '/' );
   } );

2. Reload Press This and click the site name

Result: link follows the filtered URL
