Remove unused dependencies from quickfixj-base

[Copilot]

Maven dependency analysis identified unused and incorrectly scoped dependencies in quickfixj-base.

Changes

• Removed mockito-core - No usage found in test sources
• Removed hamcrest:3.0 - Redundant explicit dependency; hamcrest-core:1.3 already available transitively via junit:4.13.2
• Fixed slf4j-api scope - Changed from compile to test (only used in FileUtilTest)

Before

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
</dependency>

After

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
    <scope>test</scope>
</dependency>

junit-vintage-engine retained - required for JUnit 4 test execution under JUnit 5.

Fixed in a293d3f. The test was checking for null after closing the stream. Also corrected the LICENSE path to "../LICENSE" since Maven runs tests from the module directory.
