Module register 

Synapse-compatible shared-secret registration backend.

Pairs with the HTTP handlers in tuwunel_api::client::admin that serve /_synapse/admin/v1/register. Owns:

1. resolution of the shared secret (from registration_shared_secret or its _file companion), performed at each use;
2. a short-lived in-memory nonce store with a 60-second TTL.

The nonce store lives in RAM rather than RocksDB on purpose: each entry’s useful lifespan is shorter than a single block-cache eviction tick, and the working set is bounded by NONCE_CAP regardless of traffic.
