Add new esplora API endpoints:
- GET /api/block/{hash}/header - returns 80-byte block header as hex
- GET /api/tx/{txid}/merkle-proof - returns merkle proof in Electrum format
Other changes:
- Fix /api/block/{hash}/raw to return binary data instead of hex
- Add unit tests for compute_merkle_proof function
- Add minipool-test check to flake.nix for CI test execution
- Fix error handling when transaction not found in block

Summary
Primary fix: The
/api/block/{hash}/rawendpoint now correctly returns raw binary block data withContent-Type: application/octet-streaminstead of hex-encoded text. This matches the real esplora API behavior (blockstream.info/mempool.space).Additional endpoints added:
/api/block/{hash}/header- returns 80-byte block header as hex/api/tx/{txid}/merkle-proof- returns JSON withblock_height,merklearray, andposDevelopment tooling:
