Merge branch 'prototype/reverse-proxy' into prototype/reverse-proxy-clusters

Combines token-based authentication from upstream with proxy clustering:
- Session keys for JWT signing (SessionPrivateKey/SessionPublicKey)
- One-time token store for proxy authentication
- Cluster-targeted updates via SendReverseProxyUpdateToCluster
- ProxyCluster field derived from domain
- OIDC validation config support
