    {{-- 
    ROOT CAUSE FIX: EventsController was limiting upcoming events to 3 with ->take(3)
    This prevented "View More" functionality from working since Blade never saw >6 events.
    
    FIXES APPLIED:
    1. Removed ->take(3) limit from EventsController index() method
    2. Added Event model scope with proper Asia/Kolkata timezone handling
    3. Added safe casts for date/time fields
    4. Blade template now receives ALL upcoming events for proper "View More" functionality
    5. FIXED: Date-time parsing without concatenation errors - parse date and time separately
    
    Static file mirrored: irqs-website/events.php
    Data mapping:
    - Date/Time: date + time fields, formatted as "M d, Y - h:i A IST" in Asia/Kolkata timezone
    - Location: location field, fallback to title if location is empty
    - Duration: duration field, fallback to "30 Minutes" if empty
    REMINDER: No labels, values only. No new CSS, match static markup exactly.
