Please Fix Localization Issues

Hi,

I found some localization issues; fixing them will be more helpful for plugin users.

1. Please complete the translation project (Development and Stable) on https://translate.ww.wp.xz.cn/projects/wp-plugins/header-footer-code-manager/. When the translation project is ready for all languages, then you don’t need to package PO and MO files into plugin ZIP file.

2. Some strings can be translated but not showing. I list them the following (includes\hfcm-add-edit.php):
2.1. Line 250
Original: $larray = array( 'header' => 'Header', 'before_content' => 'Before Content', 'after_content' => 'After Content', 'footer' => 'Footer' );
Suggestion: $larray = array( 'header' => __( 'Header', '99robots-header-footer-code-manager' ), 'before_content' => __( 'Before Content', '99robots-header-footer-code-manager' ), 'after_content' => __( 'After Content', '99robots-header-footer-code-manager' ), 'footer' => __( 'Footer', '99robots-header-footer-code-manager' ) );

2.2. Line 252
Original: $larray = array( 'header' => 'Header', 'footer' => 'Footer' );
Suggestion: $larray = array( 'header' => __( 'Header', '99robots-header-footer-code-manager' ), 'footer' => __( 'Footer', '99robots-header-footer-code-manager' ) );

2.3. Line 271
Original: <?php $devicetypearray = array( 'both' => 'Show on All Devices', 'desktop' => 'Only Desktop', 'mobile' => 'Only Mobile Devices' ) ?>
Suggestion: <?php $devicetypearray = array( 'both' => __( 'Show on All Devices', '99robots-header-footer-code-manager' ), 'desktop' => __( 'Only Desktop', '99robots-header-footer-code-manager' ), 'mobile' => __( 'Only Mobile Devices', '99robots-header-footer-code-manager' ) ) ?>

2.4. Line 272
Original: <?php $statusarray = array( 'active' => 'Active', 'inactive' => 'Inactive' ) ?>
Suggestion: <?php $statusarray = array( 'active' => __( 'Active', '99robots-header-footer-code-manager' ), 'inactive' => __( 'Inactive', '99robots-header-footer-code-manager' ) ) ?>
