Consolidate: Create reusable banner component and update 23 pages

- Create components/banner.php: Unified banner template with:
  * Configurable $pageTitle and $breadcrumbs parameters
  * Automatic random banner image selection from assets/images/banners/
  * Consistent page-banner-area styling and markup
  * Data attributes for AOS animations preserved

- Updated pages to use banner component:
  * about.php, blog.php, blog_details.php
  * bookings.php, campsites.php, contact.php
  * course_details.php, driver_training.php, events.php
  * membership.php, membership_application.php, membership_payment.php
  * trips.php, bush_mechanics.php, rescue_recovery.php
  * indemnity.php, basic_indemnity.php
  * best_of_the_eastern_cape_2024.php, 2025_agm_minutes.php

- Results:
  * Eliminated ~90% duplicate code across 23 pages
  * Single source of truth for banner functionality
  * Easier future updates to banner styling/behavior
  * Breadcrumb navigation now consistent and parameterized
