Add bot probe filter middleware and Sentry noise suppression

Browse source 
Block common bot scanning paths (wp-admin, .env, .php, etc.) in Express
before React Router handles them, preventing spurious Sentry errors.
Also filter Sentry events for React Flight protocol probes ($1:aa:aa
multipart body pattern) and any remaining bot-path 404 noise.
