fix(php-shim): use PhpMixed::to_bool() for PHP truthy casts

Several call sites coerced PhpMixed to bool via `.as_bool()` (which
only matches a literal Bool variant) where the corresponding PHP code
does a plain `(bool)` cast or truthy check (isset()/array_key_exists()
+ implicit bool conversion). This silently dropped truthy non-bool
values (e.g. String("true"), String("1"), Int(1)) to their unwrap_or
default instead of PHP's actual truthy result. Switched these sites to
PhpMixed::to_bool(), which implements PHP's full truthy-cast rules.
