feat(indexer): handle PiecesAddedV2 events

[Kubuxu]

Closes #101.

Summary

Add indexer support for the compact PiecesAddedV2 event introduced by FilOzone/pdp#300.

• update generated contract ABIs from the head commit of chore: update PDP dependency filecoin-services#596
• register a PDPVerifier:PiecesAddedV2 handler
• reconstruct PieceCIDv2 bytes from the packed header and root
• derive consecutive piece IDs from firstPieceId
• store V2 events in the existing pdp_pieces_added table
• retain the legacy PiecesAdded ABI and handler for historical indexing

Large additions emitted as multiple PiecesAddedV2 batches produce separate rows, identified by their block hash and log index.

CID reconstruction

PackedCid.header is right-aligned in a bytes32. Reconstruction removes only the leading zero bytes, preserves zero bytes within the header, and appends the complete 32-byte root. The resulting bytes use the existing PieceCIDv2 decoder.

Verification

• npm test — 13 tests passed
• npm run typecheck
• synthetic PiecesAddedV2 ABI decode and packed-CID smoke test

Pull request overview

Adds indexer support for the new compact PDPVerifier.PiecesAddedV2 event by decoding the packed CID representation and persisting it into the existing pdp_pieces_added table, while retaining the legacy PiecesAdded handler for historical indexing.

Changes:

• Register a PDPVerifier:PiecesAddedV2 handler and persist decoded pieces into pdp_pieces_added.
• Implement packed-CID reconstruction (header + root) plus consecutive piece ID derivation helpers.
• Update generated ABIs to include PiecesAddedV2 and related upstream contract changes, and add a focused unit test suite for decoding.

fine .. but you're pulling in duplicate events now that were deduped upstream, CDNPaymentRailsToppedUp, CDNServiceTerminated, DataSetAbandoned, RailRateUpdated are now in there twice. Can you see if you can get AI to script up a dedupe in generate-abis.sh? It should be able to find a union and exclude from each one.

we also have some new things to track in here, deletions and authorizer, but we could do those separately
