FPM: Consider escaping script in status

Description

Currently the script field in status is not escaped for neither JSON, HTML nor XML. It should be investigated if any of the characters requiring escape can get to the script filename. This is very unlikely issue in practice but potentially theoretical possible so it might be a good idea to address it.

The thing to try would be to have a script whose path needs to be escaped. The server might be able to access with URL escape that is eventually transformed to the path with a character requiring an escape. This needs some testing if it's even possible.

Comienza probando la salida de estado de PHP-FPM con un script cuya ruta contenga caracteres que requieran escaping, cubriendo JSON, HTML y XML. Determina si el escaping de URL puede producir una ruta de ese tipo y si el campo script se emite de forma segura; se considera terminado cuando se haya confirmado el comportamiento y se haya abordado cualquier escaping necesario.
