Distributed Token & Caching Service

A Spring Boot token and caching service backed by Redis, shared across replicas to serve repeated verification.

Repeat lookups stopped paying for the downstream call again
Onboarding throughput improved through high-volume periods
Cache shared across replicas, so it is correct rather than lucky
