Update address filter hashing to match provider spec - NIT-4754

[mahdy-nasr]

Summary

• Update hashing algorithm in scripts/config.ts to match nitro#4586
• Salt generation changed from random hex bytes to UUID (crypto.randomUUID())
• Hash input changed from binary SHA256(salt_bytes + addr_bytes) to string SHA256("{uuid}::0x{address}")
• Fix MinIO healthcheck in docker-compose.yaml (curl → mc ready local)

Testing

• Verified hash output matches the Go implementation using known test vector (salt: 3ccf0cbf-..., address: 0xddfAbCdc..., expected hash: 0x8fb74f22...)
• Full E2E test: started testnode with --l2-tx-filtering, added address to filter list, confirmed tx was rejected, removed address, confirmed tx succeeded again
