jdbc-v2: Issue with parameter data type

## Description

When running a prepared statement with `COALESCE` and a date, the execution fails due to type.

Am not entirely sure whether it's an issue with the JDBC driver (which serializes the date as a String in `PreparedStatementImpl#encodeObject` - nothing wrong with that) or the server (which should deserialize it with the proper type, or `COALESCE` which should handle types better - see https://github.com/ClickHouse/ClickHouse/issues/57292 , although most other databases handle this use case).

### Steps to reproduce

See the code below.

### Error Log or Exception StackTrace

```
Caused by: com.clickhouse.client.api.ServerException: Code: 386. DB::Exception: There is no supertype for types Date32, String because some of them are String/FixedString/Enum and some of them are not: In scope SELECT COALESCE(date, '2025-12-31') FROM test_local_date. (NO_COMMON_TYPE) (version 25.8.7.3 (official build))
at com.clickhouse.client.api.internal.HttpAPIClientHelper.readError(HttpAPIClientHelper.java:403)

```

### Expected Behaviour

The query should return without error.

### Code Example

```java
@Test
void required_testJdbcWithLocalDate() throws Exception {
final String url = "jdbc:ch://localhost:" + SERVER.getFirstMappedPort();

final Properties info = new Properties();
info.put("user", SERVER.getClickhouseUser());
info.put("password", SERVER.getClickhousePassword());

try (final Connection conn = DriverManager.getConnection(url, info)) {
conn.prepareStatement("CREATE TABLE test_local_date"
+ " (id Int64, date Nullable(Date32)) ENGINE = MergeTree() ORDER BY id").execute();
conn.prepareStatement("INSERT INTO test_local_date VALUES (1, null)").execute();
try (final PreparedStatement preparedStatement = conn.prepareStatement("SELECT COALESCE(date, ?) FROM test_local_date")) {
preparedStatement.setObject(1, LocalDate.of(2025, 12, 31));
preparedStatement.executeQuery();
}
}
}

```

### Configuration

#### Client Configuration

#### Environment
* [ ] Cloud
* Client version: clickhouse-jdbc 0.9.4
* Language version:
* OS:

#### ClickHouse Server
* ClickHouse Server version: 25.8.7.3

Commencez par la reproduction JDBC fournie et examinez PreparedStatementImpl#encodeObject, que le rapport identifie comme le point de sérialisation des dates. Exécutez la requête avec la version de ClickHouse Server indiquée et déterminez si l’échec relève de l’encodage des paramètres, de la désérialisation côté serveur ou de la gestion des types de COALESCE ; c’est terminé lorsque la requête s’exécute sans erreur.
