Subject: [PATCH] fix(shared): handle Prisma errors in GlobalExceptionFilter to
 return proper HTTP status codes

Prisma errors (P2025 record not found, P2002 unique constraint, P2003 foreign key)
were falling through to the catch-all handler and returning 500 Internal Server Error
instead of appropriate 404/409/400. This caused GET /listings/:id with a non-existent
ID to return 500 when the Prisma layer threw before the application null check.
