Add JobSpecReporter service for OCR2 job spec telemetry via Beholder

[thomjg]

Relevant ticket: DF-24042

Summary

Adds a new JobSpecReporter service that emits full job-spec telemetry via Beholder for active OCR2 jobs. This gives internal teams visibility into running job configurations.

What's added

Proto schema (core/services/nodestatusreporter/jobspec/events/)

• job_spec.proto with JobSpecEvent, OCR2OracleSpecInfo, OCR2EVMRelayConfig, and OCR2MedianPluginConfig messages. All 21 fields of OCR2OracleSpec are covered. Raw JSON passthroughs (relay_config_json, plugin_config_json, onchain_signing_strategy_json) are included alongside typed sub-messages to ensure forward compatibility.
• Mirrors the existing bridgestatus/events/ layout (emit.go, generate.go, types.go).

JobSpecReporter service (core/services/nodestatusreporter/jobspec/)

• Mirrors BridgeStatusReporter exactly: same services.Engine pattern, HealthReport(), disabled-early-return in start()`.
• Hourly heartbeat via services.NewTicker emitting a JobSpecEvent for each active job that passes the shouldEmit gate.
• Immediate create / delete events via a new job.Listener registered with job.Spawner — covers both FMS-driven approvals and manually created jobs.
• Proposal lifecycle fields (proposed_at, approved_at, accept_latency_seconds) populated from feeds.ORM; silently omitted for manually created jobs.
• Bridge names extracted from the top-level observationSource DOT DAG only (not sub-pipelines).

job.Spawner listener hook (core/services/job/spawner.go)

• New Listener interface with OnJobStarted / OnJobStopped.
• RegisterListener(Listener) added to the Spawner interface.
• Listeners are called in a panic-safe, non-blocking goroutine after successful CreateJob and after DeleteJob.

feeds.ORM (core/services/feeds/orm.go)

• Adds GetJobProposalByExternalJobID — a read-only SELECT mirroring GetJobProposalByRemoteUUID.

Config ([JobSpecReporter] TOML section)

• Enabled — defaults false.
• PollingInterval — defaults 1h, minimum 1m.
• EnabledOCR2PluginTypes — allowlist of OCR2 plugin types to emit for; defaults ["median"]. Set to [] to emit for all OCR2 plugin types.
• EmitNonOCR2Jobs — emit the generic envelope for non-OCR2 jobs; defaults false.

Initial rollout: only ocr2median jobs emit by default. Widening to other job types is a config change, no code change required.

Is there a need for a custom Close() here?

[thomjg]

Shouldn't be a need for it, services.Engine stops the goroutine; same for BridgeStatusReporter which has a similar implementation.
