Note

Medium Risk
Medium risk because it changes how proven aggregations are persisted and how invalidity proofs are fetched by introducing new injected handlers/providers; incorrect wiring could break aggregation finalization or metrics updates.

Overview
Refactors ProofAggregationCoordinatorService to remove direct dependencies on AggregationsRepository and ForcedTransactionsDao by introducing injected abstractions: AggregationProofHandler (persists proven aggregations and updates highest/consecutive aggregation trackers) and InvalidityProofProvider (supplies invalidity proof indexes).

Updates ConflationApp wiring to construct and pass AggregationProofHandlerImpl, InvalidityProofProviderImpl, and an externally-created AggregationL2StateProviderImpl (and reuses a single l2MessageService instance). Tests are adjusted to mock the new interfaces and validate the aggregation flow with the new injection points.
