feat: add synced gRPC healthcheck (#7867)

This pull request adds support for gRPC health checking to the Minotari
node. The main changes introduce a health reporter that tracks the
node's state via the state machine and updates the gRPC health status
accordingly. This allows external systems to check the node's readiness
and health using the standard gRPC health check protocol.

**gRPC Health Checking Integration:**

* Added the `tonic-health` dependency to `Cargo.toml` for gRPC health
checking support.
* Updated the `run_grpc` function in `lib.rs` to optionally accept a
`StateMachineHandle`, set up a `HealthReporter`, and add the gRPC health
service to the server. The health status is updated based on the node's
state.
