feat: convert WordOps from Nginx to OpenLiteSpeed + LSPHP + LSCache

Complete conversion of the WordOps stack from Nginx + PHP-FPM to
OpenLiteSpeed + LSPHP + LSCache. This is a full rewrite across all 7
phases of the codebase:

- Foundation: OLS paths, variables, services, removed pynginxconfig dep
- Templates: 11 new OLS mustache templates, removed nginx-specific ones
- Stack: stack_pref, stack, stack_services, stack_upgrade, stack_migrate
- Site: site_functions, site, site_create, site_update
- Plugins: debug, info, log, clean rewritten for OLS
- SSL/ACME: acme.sh deploy uses lswsctrl, OLS vhssl blocks
- Other: secure, backup, clone, install script

Additional features:
- Debian 13 (trixie) support
- PHP 8.5 support
- WP Fort Knox mu-plugin integration (wo secure --lockdown/--unlock)
- --nginx CLI flag preserved for backward compatibility
