refactor: use SmtForest in SqliteStore

CHANGELOG.md

@@ -27,6 +27,7 @@
 * Added WebClient bindings and RPC helpers for additional account, note, and validation workflows ([#1638](https://github.com/0xMiden/miden-client/pull/1638)).
 * [BREAKING] Modified JS binding for `AccountComponent::compile` which now takes an `AccountComponentCode` built with the newly added binding `CodeBuilder::compile_account_component_code` ([#1627](https://github.com/0xMiden/miden-client/pull/1627)).
 * [BREAKING] Replaced `TransactionRequestBuilder::unauthenticated_input_notes` & `TransactionRequestBuilder::authenticated_input_notes` for `TransactionRequestBuilder::input_notes`, now the user passes a list of notes which the `Client` itself determines the authentication status of ([#1624](https://github.com/0xMiden/miden-client/issues/1624)).
+* Updated `SqliteStore`: replaced `MerkleStore` with `SmtForest` and introduced `AccountSmtForest`; simplified queries ([#1526](https://github.com/0xMiden/miden-client/pull/1526), [#1663](https://github.com/0xMiden/miden-client/pull/1663)).
