Pull request overview

This PR adds extensive unit tests to improve code coverage for SQLServerPreparedStatement, SQLServerDatabaseMetaData, and SQLServerCallableStatement, with a focus on Azure DW branches, batch/bulk-copy behavior, and a wide range of callable parameter getter/setter APIs.

Changes:

• PreparedStatementTest: Adds tests for null SQL in prepareStatement, bulk-copy batch edge cases (empty batches, column count mismatches, unsupported Azure DW types), SQL parsing around dots/comments, and batch execution error handling, including OUT/INOUT parameter validation.
• DatabaseMetaDataTest: Adds Azure DW-focused tests for getIndexInfo, getColumns, getFunctionColumns, and foreign key-related APIs, including column/type mapping validation and empty-result behavior.
• CallableStatementTest: Adds broad coverage for time/date getters and setters (with/without Calendar), deprecated getBigDecimal overloads, stream/LOB setters, setObject and registerOutParameter SQLType overloads, uniqueidentifier handling, and unsupported URL/RowId getters/setters.

File	Description
src/test/java/com/microsoft/sqlserver/jdbc/unit/statement/PreparedStatementTest.java	New tests exercise bulk-copy batch edge cases, Azure DW unsupported types, SQL parsing with schema/table dots and comments, and batch exception behavior; also adds an OUT-parameter-in-batch validation test, but unintentionally removes the assertFalse static import required by existing tests.
src/test/java/com/microsoft/sqlserver/jdbc/databasemetadata/DatabaseMetaDataTest.java	Adds Azure DW coverage for getIndexInfo, getColumns, function metadata, and foreign-key-related APIs, including reflection-based manipulation of internal mappings and checks for column/type alignment and empty-result handling.
src/test/java/com/microsoft/sqlserver/jdbc/callablestatement/CallableStatementTest.java	Extends callable statement coverage across time/date APIs, numeric precision/scale handling, TVP/structured parameters, various stream and LOB setters, SQLType-based setObject/registerOutParameter overloads, uniqueidentifier support, and “not supported” URL/RowId paths.
