The Chapters/Mangas aggregation views accept an OCR ?text= filter and the
page search intersects tags, but the client dropped both: any text query
collapsed every view into a flat page search that discarded the selected tag
and grouping. Add text to AggregateOptions, thread it into
listTaggedChapters/listTaggedMangas, and rework the search loader so a
tag-scoped view runs the aggregation (optionally text-filtered) and the page
search passes the selected tag.
