Fix critical Twig filter error in product selector template

Browse Source 
Fixed "Unknown 'esc_attr' filter" error that occurred when rendering
the product selector template. The issue was caused by WordPress
escaping functions being registered only as Twig functions, not filters.

Changes:
- Added TwigFilter registrations for esc_html, esc_attr, esc_url
- Template now supports both filter syntax (|esc_attr) and function syntax
- Fixes compatibility issues when other plugins use their own Twig instances
- Version bump to 1.1.5

This resolves the bug documented in logs/fatal-errors-2025-12-31.log
