fix: resolve GraphQL request hang in Fastify integration

- Pass FastifyRequest/FastifyReply directly to yoga.handleNodeRequestAndResponse
  per the official graphql-yoga Fastify integration docs. Yoga v5 uses req.body
  (already parsed by Fastify) when available, avoiding the dead raw stream issue.
- Add proper TypeScript generics for server context including db and redis
- Wrap sendVerification/sendPasswordReset in try/catch so missing SMTP
  does not crash register/requestPasswordReset mutations
- Fix migrate.ts path resolution to work with both tsx (src/) and compiled (dist/)
- Expose postgres:5432 and redis:6379 ports in compose.yml for local dev
