• Multiple styling adjustments and fixes throughout the plugin UI.

• Fixed an issue where code type selection for individual code snippets was still visible even after saving.
• Fixed an issue where the next page buttons in the snippets table was still showing as active even when viewing the last page.
• Fixed an issue where stylesheets with protocol-relative URLs were not getting parsed for used CSS.
• Disabled lint markers for HTML code snippets, as they do not currently work for combined HTML and inline PHP code.
• Removed unnecessary instances of perfmatters-lazy-youtube class from lazy loading inline styles. All lazy loading video features are now using a shared perfmatters-lazy-video class.

• Translation updates.
