feat: Detect fake UK universities using naming patterns

Add detection for institutions that follow UK university naming
conventions (e.g., "University of the Peak District") but aren't
in the recognised institutions list. These are now flagged as
"Suspicious" with a -15 point penalty instead of just "Unknown".
