jwinterm 707613c92b feat: router middleware (CORS, body limit, timeout, compression, tracing)
Layer global middleware onto build_router (applies to every route, shared by
main + the test harness):
- CORS: configurable allowed origins via CORS_ALLOWED_ORIGINS; empty -> allow
  any origin, which is safe here because auth is a Bearer token (no cookies, no
  ambient credentials). Credentials are never allowed.
- Body limit: 1 MiB global backstop (handlers already validate tighter per
  field); /wallet/lws/submit_tx overrides to ~2 MiB+ for raw Monero tx hex.
- Timeout: 60s request backstop (above the chain clients' ~30s timeouts, so
  their errors surface first; bounds any slow handler). Uses the http-aware
  tower_http TimeoutLayer (-> 408), not tower::timeout (fallible, rejected by
  axum's Infallible Router).
- gzip compression + request tracing (outermost).

Adds cors_allowed_origins config + the tower-http "timeout" feature. Per-IP
rate limiting is deliberately separate (needs ConnectInfo) — next commit.

All gates green; integration tests pass through the layered router (CORS/timeout/
compression/body-limit are oneshot-safe). openapi unchanged.
