CVE-2026-48806: Twig Sandbox Bypass Array Keyscve-2026-48806-twig-sandbox-bypass-array-keys

Dynamic array key compilation misses a fallback to cast expressions as StringCastUnary. This allows objects to be used as array keys, which coerce to string bypassing the Twig sandbox `ensureToStringAllowed()` security policy check.
