Fix Perl Site Dependencies

My Perl-based site has suddenly stopped loading and the error log points to a stack of missing CPAN modules. I need someone to jump in via SSH, install every dependency, clear any additional breaks you uncover and confirm the application boots without warnings.

Core modules already flagged as missing:
• Crypt::CBC
• Crypt::Cipher::AES
• Crypt::SSLeay
• DBI
• DBD::mysql
• XML::XPath
• JSON

Feel free to pull in any secondary libraries these require—whatever it takes to restore full functionality. Once the environment is clean, run a quick health check on all pages so I know the fixes hold under typical usage.

Acceptance is simple: the site loads normally in a browser, each listed module passes a `perl -M<Module> -e1` test, and there are no Perl warnings or 500 errors in the server log.

SSH credentials and sudo access will be supplied as soon as we start.
