MLE-23146 Address compile warnings in src/main/java

[rjrudin]

Copilot got a little carried away and knocked out some issues in src/test/java too. More to come after this PR.

Addresses unchecked and deprecation warnings by:

• Adding compiler arguments to include deprecation details.
• Removing unnecessary finalize() methods.
• Replacing raw types with parameterized types in test classes.
• Replacing StringBuffer with StringBuilder.
• Using isEmpty() instead of checking length > 0.
• Replacing Boolean constructor with boolean literal.
• Various other minor code improvements.

Consider using StandardCharsets.UTF_8 instead of the hardcoded "UTF-8" string to avoid potential typos and improve code maintainability.

Suggested change

	contents = URLEncoder.encode(uri, "UTF-8").replaceFirst(".*", regex);
	contents = URLEncoder.encode(uri, StandardCharsets.UTF_8.name()).replaceFirst(".*", regex);

[nitpick] Consider using Path.of() or Paths.get() with proper path separators instead of string concatenation for file paths to improve cross-platform compatibility.

Suggested change

	JsonParser jParser = jfactory.createParser(new File("src/test/java/com/marklogic/client/functionaltest/data/" + filename));
	JsonParser jParser = jfactory.createParser(new File(Path.of("src", "test", "java", "com", "marklogic", "client", "functionaltest", "data", filename).toString()));
