Previously, the AI helper's tag suggester could recommend tags the selected cate…gory doesn't allow — it filtered candidates only by tag visibility and was never told the composer's category, so a user could pick a suggestion they then couldn't submit (while adding the same tag manually was correctly blocked). This change routes the suggested tags through the same `DiscourseTagging.filter_allowed_tags` rules the tag chooser and topic-save validation use, scoped to the selected category and already-selected tags, so only submittable tags are suggested.
