Add response schema log support

[gonzauy]

Adds support for logging response-schema validation failures (including the route pattern) via a new logResponseSchemaErrorsFn option, with accompanying docs and cucumber coverage.

Changes:

Introduces logResponseSchemaErrorsFn in public options/types and wires it through app creation into the async converter.
Extends response-schema handling to optionally log schema errors and/or reject invalid responses with HTTP 400.
Adds an advanced-example route + cucumber steps/scenario to verify the callback is invoked with a route-pattern path; updates docs and version.
