Enhance cleanup to include /poi/ and /entities/ folders

[bierdosenhalter]

Currently, ChunkCleaner only moves/deletes region files, but it doesn't handle the /poi/ and /entities/ folders. This causes errors like "Entity UUID already exists", even though the server doesn't crash. Please add support to clean/move these folders during region cleanup to prevent these errors.

// processRelatedFiles handles moving or deleting the /poi/ and /entities/ files
func processRelatedFiles(rootDir, filename string, move bool, destDir string, verbose bool) {
	subFolders := []string{"poi", "entities"}

	baseName := filepath.Base(filename)
	regionFilePath := filepath.Join(rootDir, "region", baseName)

	for _, folder := range subFolders {
		srcPath := filepath.Join(rootDir, folder, baseName)
		destPath := ""
		if move {
			destPath = filepath.Join(destDir, folder, baseName)

		if move {
			// Ensure destination folder exists
