perf(console): decouple invocation telemetry writes

Move Axum management and gateway adapters into a dedicated module while preserving the existing public routers and response contracts.

Replace per-invocation full snapshots with a bounded asynchronous writer that batches metric deltas and events. Serialize it with control snapshots, flush before lifecycle persistence and graceful shutdown, and keep invocation results independent from telemetry failures.

Enable the Runtime compilation cache beside the Console artifact directory and verify metric recovery across a lifecycle flush.
