feat(rotel-visual): end-to-end OTLP ingestion → classification → visualization pipeline#65

…alization pipeline - Add main.rs binary entry point so rotel-visual runs as a standalone server. - Add OTLP JSON ingestion endpoints: POST /v1/logs, /v1/metrics, /v1/traces. All return 202 Accepted with classification column metadata. - Integrate ledger-core::observability::LogShapeClassifier into rotel-visual. Incoming logs are classified against built-in rules (e.g. gpu-driver fault). - Broadcast classified artifacts to WebSocket subscribers at /ws/telemetry. - Add in-memory ring buffer (capacity 100) that replays to new WebSocket connections before live updates begin. - Update dashboard HTML to show classified artifacts panel. - Add anyhow dependency for error handling. - Expand tests: OTLP ingestion (logs/metrics/traces), invalid JSON rejection, classification broadcast, ring buffer replay. All 8 tests pass.

Pull request overview
Adds a standalone rotel-visual server that ingests OTLP JSON, classifies log shapes using ledger-core observability utilities, and streams/replays telemetry to a browser dashboard over WebSockets.
Changes:
- Introduces a
main.rsbinary entrypoint for runningrotel-visualas a standalone server. - Adds OTLP JSON ingestion endpoints (
/v1/logs,/v1/metrics,/v1/traces) and integratesLogShapeClassifierfor log classification. - Implements websocket broadcasting with an in-memory ring buffer and updates the dashboard UI with a “Classified Artifacts” panel.

- Remove useless String->String .into() conversions (clippy) - Handle serde_json::to_string() errors instead of panicking (unwrap) - Escape all user-derived fields before innerHTML interpolation (XSS) - Take Json<OtlpLogsRequest> directly, eliminating clone + double-deser - Extract OTLP resource and record attributes into OTelLogRecord - Make create_app()/run_server() return Result instead of panicking - Update main.rs to handle run_server() Result - Rename misleading test names to match actual coverage - Update all test call sites to use create_app().expect(...)"
