deps: upgrade fastify v4 to v5 line to fix dependabot alerts

Fastify 4.x is EOL with no backported fixes; all six open alerts
(critical http-proxy header stripping, static path traversal + auth
bypass, fastify body-validation bypass / host spoofing / DoS) are only
patched on the v5 line. Bump fastify to 5.12.0 and all @fastify/*
plugins to their v5-compatible majors, and migrate the two options v5
deprecated (disableRequestLogging -> logController, maxParamLength ->
routerOptions).
