refactor: extract business logic from listeners into services

[rorybyrne]

Summary

• Move business logic from EventListeners into dedicated Service classes
• Listeners now delegate to services (thin adapters)
• Enables unit testing without event infrastructure
• Enables reuse from multiple entry points (CLI, API, scheduled jobs)

Changes

Listener	Service	Lines removed
IngestFromUpstream	IngestService	~50
ConvertDepositionToRecord	RecordService	~35
ProjectNewRecordToIndexes	IndexService	~10

Test plan

• Unit tests for each new service (10 tests total)
• Existing ingestor tests still pass
• Lint and type checks pass

Closes #14
