Harden admin settings output escaping

[MaximillianGroup]

Summary

• document the admin settings controller and its constants to satisfy repository documentation rules
• escape all rendered settings UI strings and add a failure guard when JSON encoding fails so diagnostics remain safe for administrators
• separate the snapshot section description from the viewer output to avoid duplicate rendering and keep markup outside the form

Testing

• composer lint (fails: vendor/bin/phpcs missing in the container)
