Fix CodeQL help generation paths in build-and-publish workflow

[Copilot]

The build-and-publish (java) workflow was failing during codeql generate query-help because the .qhelp files referenced sample sources using paths that are not valid from src/main/ql. This updates the sample references to the actual Java source locations and fixes a related import issue in one sample class.

• QHelp sample resolution

  • Update all <sample src="..."> references in the query help files to use paths relative to src/main/ql.
  • This allows CodeQL help generation to resolve the insecure/secure sample pairs used in the published documentation.

• Sample source cleanup

  • Add the missing HttpServerOptions and JksOptions imports in SecureCorsServer.java.
  • Keeps the referenced secure example self-consistent once it is pulled into help generation and local builds.

• Representative change

  - <sample src="InsecureHttpServer.java" />
  + <sample src="../java/org/carlspring/security/vertx/http/InsecureHttpServer.java" />

• Files updated

  • src/main/ql/InsecureCorsHttpOrigin.qhelp
  • src/main/ql/InsecureCorsWildcardOrigin.qhelp
  • src/main/ql/InsecureHttpServer.qhelp
  • src/main/java/org/carlspring/security/vertx/http/SecureCorsServer.java
