- public/admin/logs.php: new page tailing nginx error/access + PHP-FPM logs.
Selector for log file and line count (50/100/200/500, default 100).
Lines reversed (newest first), colour-coded by severity, numbered gutter.
Graceful degradation when exec() unavailable or file unreadable (dev msg).
- templates/admin/head.php: 'Journaux' nav link added after 'Statut'.
- public/admin/status.php: remove curl_close() call deprecated in PHP 8.5
(no-op since PHP 8.0); replace with unset($ch) to silence the warning
that was leaking raw text above the page output.
