Fix NodeNext interop with CJS dependencies on Node 24

Under module:NodeNext, default imports of CJS packages can resolve to the
module namespace rather than the runtime export, and some dep bumps moved
public types out of the package's barrel. Adjusts four call sites:
- api-gateway cache-provider: switch ioredis to a named import so Redis
  resolves as a class.
- auth-service metrics: import expressMiddleware by name from
  prometheus-api-metrics instead of the default.
- auth-service meeco.service: drop the base64url package in favor of
  Buffer.toString('base64url') (built into Node since 16).
- policy-service math-context: derive BoxedExpression from
  ComputeEngine['box']'s return type since @cortex-js/compute-engine 0.27
  no longer re-exports the interface at the top level.
