Adds a dedicated Prometheus metrics endpoint on port 9098 (configurable
via METRICS_PORT env var) with counters for HTTP requests, histograms for
request duration, gauges for uptime and active WebSocket connections, and
counters for WebSocket messages. Metrics are registered using once_cell
Lazy statics with abort-on-failure to satisfy the crate's deny(unwrap)
lint policy.

Replace direct tracing_subscriber::fmt::init() calls with the unified
common::observability::init_observability() in api_gateway, web-gateway,
data_acquisition_service, broker_gateway_service, and trading_agent_service.
All 8 services now emit JSON logs + OTLP traces to Tempo.

Web-gateway routes through api-gateway for the foxhunt.tli proto, but
api-gateway requires JWT Bearer auth on all gRPC requests. This adds a
service_auth module that mints short-lived service JWTs (matching the
api-gateway's expected claims: iss, aud, roles, permissions) and injects
them into all 15 REST proxy calls and 4 gRPC stream bridges.

- Add ohlcv_bars table migration (050) for trading_service prediction loop
- Fix kube-state-metrics RBAC: add admissionregistration.k8s.io and
certificates.k8s.io API groups to suppress forbidden errors
- Fix web-gateway gRPC stream reconnect: detect Unimplemented via both
status code and error message text (proxy may remap codes)
- Add automated migration step to CI deploy pipeline with tracking table
(_applied_migrations) so migrations are applied before service rollouts

- Disable file logging in init_observability — use console-only (stdout).
Containerd captures stdout, Promtail ships to Loki. Eliminates
"Failed to create log directory: Permission denied" errors on 3 services.
- Remove LOG_DIR env vars and /app/logs emptyDir volumes from 5 deployments.
- Add OTEL_EXPORTER_OTLP_ENDPOINT=tempo to 5 services that were missing it
(api-gateway, web-gateway, data-acquisition, trading-agent, broker-gateway).
- Make OTLP tracing init non-fatal — services degrade gracefully if Tempo is
unavailable instead of failing entire observability stack.
- Stop web-gateway gRPC stream retry on Unimplemented status. When trading-service
doesn't implement streaming endpoints, log once and stop instead of retrying
every 60s indefinitely.

- Add dimension validation in DQN, PPO, Mamba2, TGGN, TLOB, Liquid,
KAN, xLSTM, Diffusion constructors (fail-fast on zero-dim inputs
that would cause CUDA_ERROR_INVALID_VALUE at runtime)
- Add num_unknown_features > 0 guard to TFT (temporal input required)
- Fix 12 dead-code/unused warnings in test compilation
- Remove opt-level=3 and codegen-units=1 from target rustflags
(was forcing O3 + single-thread codegen on dev/test builds)
- Remove hardcoded jobs=16 cap (cargo now auto-detects CPU count)
- Switch linker to clang+lld (2-5x faster linking)
