External HR Picture values are relative paths; the resolver hardcoded
/static/employees/ (which the SPA then mounts under the subpath, e.g.
/ops/static/...), but sites like WJ serve those photos from the
classic EmployeeDBAPP on another URL entirely. New setting
employee_photo_base_url (blank keeps the old behavior; a full URL like
https://host/EmployeeDBAPP/images/ passes through withBase untouched),
declared in the plugin config schema.
