refactor(php-shim): replace literal sprintf calls with format!

Convert every sprintf() call with a compile-time literal format string to
format!, implementing Display for PhpMixed (delegating to php_to_string) so
PhpMixed values render with PHP string semantics through {}. Also merge the
format!-wrapped and conditional-literal dynamic sites into single format!
calls. Genuinely runtime format strings (table styles, configurable error
messages, command synopsis, progress-bar modifiers, regex-built messages)
still go through sprintf.
