Pull request overview

This PR adds explicit origin tracking for siacoin UTXOs and exposes that information via a new decorated consensus block API.

Changes:

• Introduces SiacoinOrigin/CreatedSiacoinElement in the wallet layer and extends applyChainUpdate to infer and attach origins for all siacoin UTXO sources (transactions, siafund claims, miner/foundation payouts, V1/V2 contract payouts).
• Extends the SQLite schema (siacoin_elements) with origin columns (via init.sql and migration v9), plus encoding helpers and storage wiring in addSiacoinElements, and adds Store.DecorateConsensusBlock to read and expose origin data.
• Adds new public API types (ConsensusBlock, decorated transaction/input/output types), routes /consensus/blocks/:id through DecorateConsensusBlock, wires the store into api.NewServer, and adds tests for DecorateConsensusBlock and API usage updates.

File	Description
wallet/update.go	Adds SiacoinElementSource, SiacoinOrigin, and CreatedSiacoinElement, extends AppliedState, and augments applyChainUpdate to compute and attach UTXO origins for all relevant siacoin creation paths.
persist/sqlite/migrations.go	Adds migrateVersion9 to introduce origin_source, origin_transaction_id, and origin_transaction_index columns to siacoin_elements.
persist/sqlite/init.sql	Updates the initial schema for siacoin_elements to include the new origin columns and comments describing their purpose.
persist/sqlite/encoding.go	Adds generic nullDecodable[T] to support scanning nullable Sia-encoded values (used for nullable origin IDs).
persist/sqlite/consensus.go	Switches addSiacoinElements to accept wallet.CreatedSiacoinElement and persist origin fields; adds Store.DecorateConsensusBlock to build api.ConsensusBlock by querying UTXO origins and decorating siacoin inputs (V1 and V2).
persist/sqlite/consensus_test.go	Adds TestDecorateConsensusBlock with multiple subtests covering NULL vs complete origin fields for V1/V2 inputs and missing-element error handling.
cmd/walletd/node.go	Passes the SQLite store into api.NewServer so the API can call DecorateConsensusBlock.
api/server.go	Introduces a Store interface, extends the server struct to hold it, changes /consensus/blocks/:id to return a decorated ConsensusBlock via DecorateConsensusBlock, and updates NewServer to accept the store.
api/api.go	Defines ConsensusSiacoinInput, ConsensusV2SiacoinInput, ConsensusSiacoinOutput, ConsensusTransaction, ConsensusV2Transaction, ConsensusV2BlockData, and ConsensusBlock to represent decorated consensus data in the HTTP API.
api/api_test.go	Updates tests to pass a store into NewServer and tweaks a time equality check to use Time.Equal instead of ==.
.changeset/added_siacoin_input_origin_to_consensusblock.md	Records a minor-version changeset describing the addition of siacoin input origin data to the consensus/block API.
