Pull request overview

This PR reworks the “claimer” flow by removing the bespoke claimer repository APIs, extending the schema/model to track claim-submitted/claim-accepted tx hashes and per-app claim event scan checkpoints, and updating the claimer service to operate via the general-purpose repository interfaces.

Changes:

• Remove ClaimerRepository and Postgres claimer queries; add new epoch repo update methods for claim tx hashes.
• Extend application and epoch persistence/model with claim scan checkpoints and separate submitted/accepted claim tx hash fields.
• Rewrite claimer tick logic to iterate enabled applications, scan claim events, update epoch status/tx hashes, and optionally submit claims.

• This file removal deletes the ClaimerSuite and helper builders, but internal/repository/repotest/repotest.go still invokes NewClaimerSuite. As-is, the repotest package will no longer compile. Either keep/move these claimer repository test cases (adapted to the new schema/API) or remove the Claimer suite registration from repotest.go.

• ListEpochs now selects/scans ClaimSubmittedTransactionHash and ClaimAcceptedTransactionHash, but other epoch fetch paths (e.g., GetEpoch / GetEpochByVirtualIndex) still only populate ClaimTransactionHash. This can lead to these new fields always being nil in API responses or callers that use GetEpoch. Consider updating the other SELECT/Scan projections for consistency with the expanded model.Epoch struct.
