[ISSUE-4203][Bug] Preserve quoted program args

[hutiefang76]

What changes were proposed in this pull request

Issue Number: close #4203

This pull request updates FlinkConfigurationUtils.extractArguments(String) to split program arguments while preserving quoted segments. This prevents arguments such as Kafka properties.sasl.jaas.config='... username="user" password="pass";' from being split into multiple program arguments because of spaces inside the quoted value.

Brief change log

• Add quote-aware splitting before delegating to the existing extractArguments(Array[String]) logic.
• Keep existing array-based argument normalization unchanged.
• Add a regression test for Kafka JAAS config values with spaces and nested double quotes.

Verifying this change

This change added tests and can be verified as follows:

• Added PropertiesUtilsTestCase#testExtractProgramArgsKeepsQuotedKeyValueWithSpaces.
• Verified the new test failed before the fix because the JAAS config value was split across multiple arguments.
• Ran locally:

JAVA_HOME=$(/usr/libexec/java_home -v 17) ./mvnw -s /tmp/codex-empty-maven-settings.xml -pl streampark-common -DskipITs -DskipRat -DfailIfNoTests=false -Dtest=PropertiesUtilsTestCase test

Result: Tests run: 3, Failures: 0, Errors: 0, Skipped: 0.

• Ran the full streampark-common test target locally:

JAVA_HOME=$(/usr/libexec/java_home -v 17) ./mvnw -s /tmp/codex-empty-maven-settings.xml -pl streampark-common -DskipITs -DskipRat -DfailIfNoTests=false test

Result: Tests run: 12, Failures: 0, Errors: 0, Skipped: 0.
