AI Social Share - Modernized & Fixed Version

What's Fixed

1. Facebook OAuth URL Encoding Bug ✅

Problem: WordPress's add_query_arg() function doesn't properly URL-encode parameters that contain special characters (?, &). This caused Facebook OAuth to fail with "URL blocked" errors.

Fixed in: class-aiss-facebook.php

• build_oauth_url() - Initial OAuth redirect
• exchange_code_for_token() - Token exchange

Solution: Replaced add_query_arg() with http_build_query($params, '', '&', PHP_QUERY_RFC3986) which properly encodes all special characters according to RFC 3986 standards.

2. Disappearing Page Selector Bug ✅

Problem: After selecting a Facebook Page, the page selector disappeared and users couldn't see which page was connected.

Fixed in: class-aiss-admin.php

• Now shows prominent connection status with page name and ID
• Displays connection details in a beautiful card
• Page selector only shows during initial setup
• After connection, shows clear status with disconnect button

3. Modern UI Overhaul ✅

Completely redesigned the admin interface with:

• Beautiful gradient headers
• Modern card-based layout
• Color-coded status indicators
• Smooth animations
• Better typography and spacing
• Responsive design
• Professional color scheme (purple/blue/green gradients)
