   ### Purpose of this pull request
   
   This PR aims to improve the test coverage and stability of the DamengDB 
connector.
   Specifically, the following changes have been made:
   
   1.  **Added `DmdbDialectFactoryTest`**:
       * Verified `dialectFactoryName` and `acceptsURL` logic.
       * Tested `create` methods with different `FieldIdeEnum` configurations 
(Original, Uppercase, Lowercase).
   2.  **Enhanced `DmdbDialect` Unit Tests**:
       * Added tests for SQL generation: `getUpsertStatement`, 
`getInsertIntoStatement`, `getDeleteStatement`, `getUpdateStatement`, and 
`getRowExistsStatement`.
       * Verified table identifier parsing and quoting logic 
(`quoteIdentifier`, `tableIdentifier`).
       * Tested `needsQuotesWithDefaultValue` for various data types (String 
types vs Numeric types).
       * Verified the correct instantiation of converters and mappers 
(`TypeConverter`, `JdbcDialectTypeMapper`, `RowConverter`).
   3.  **Updated `pom.xml`**:
       * Added necessary test dependencies: `testcontainers`, `junit-jupiter`  
(for test container support).
   
   ### Does this PR introduce _any_ user-facing change?
   
   No.
   ### How was this patch tested?
   
   * **Unit Tests**: Added comprehensive unit tests in `DmdbDialectFactoryTest` 
and updated `DamengDialectContainerTest`.
   * **Local Execution**: Ran all tests locally using Maven to ensure they pass 
without errors.
