Display Term Meta by Term Name and Meta Key from the Current Post Loop, Bricks Dynamic Data Tag

Custom dynamic tag {current_term_meta:termnameslug:metakey} for Bricks Builder. Retrieves term meta values by term name and meta key on single posts (using attached terms) and term archives (using queried term). Automatically replaces the tag in dynamic content

 * Usage: {current_term_meta:termname:metakey}
 * Description:
 * - On a single post: finds attached term by name and fetches the meta value.
 * - On a term archive: uses the current queried term and fetches the meta value.
