v2.0.6 — Fix product page reel video + popup, searchable product dropdown

What's Fixed

• Reel videos now load correctly on single product pages (lazy loader was not being initialized)
• Product detail popup now opens properly (migrated from Bootstrap 4 jQuery API to Bootstrap 5 native API)
• Removed duplicate modal markup on product pages — uses single shared modal
• VideoModal (floating video player) uses correct Bootstrap 5 data attributes
• Multiselect dropdown for Related Products now opens below the trigger instead of overlapping it

What's New

• Searchable dropdown for Primary Product selection on the reel edit screen (type to filter products)
• Theme-proof CSS with high z-index overrides to prevent themes from hiding modals or video players
• Graceful fallback if Bootstrap JS fails to load on the frontend
• Proper script dependency declarations ensuring correct load order
