* fix(types): Fix use of "esModuleInterop: false"

Pino 9.8 changed its type definitions to be more correct (see pinojs/pino#2223 and linked discussions), but that causes problems for projects that don't set "esModuleInterop: true" (see pinojs/pino#2253).

Doing a namespace import (so fastify.d.ts can see pino's types) should address this.

* Switch to named exports

Now that Fastify simply re-exports Pino types, its "Standard Fastify logging function" docblock has little or no effect.  (For example, VS Code goes straight to Pino's definition.)
