Introduce `EventHandler` trait in `dash-spv` with default no-op methods and make `DashSpvClient` generic over it (`H: EventHandler`, default `()`). The handler is passed at construction time and stored as `Arc<H>`: - `DashSpvClient::new()` takes `Arc<H>` and emits initial progress via `on_progress()` immediately after construction - `run()` subscribes to internal channels and dispatches events to the stored handler via monitoring tasks — no handler parameter needed - `impl EventHandler for ()` provides a zero-cost no-op default - `FFIEventCallbacks` implements `EventHandler` directly, eliminating the `FFIEventHandler` wrapper - FFI: callbacks pass to `dash_spv_ffi_client_new()`, `run()` is parameter-less - Add `TestEventHandler` that bridges events back to tokio channels for ergonomic `select!`-based integration tests - Add `LoggingEventHandler` to CLI binary
Without `on_error`, fatal errors from the background sync task were silently swallowed and the CLI would hang waiting for Ctrl+C.
