FEATURE: Bulk topic tagging allowing restricted operations on sole categories (#26602)

The bulk actions menu for topics has multiple options to work
with tags on topics (append, replace, remove). Our tagging system
along with categories allows for some complicated tag restrictions
to be applied via tag groups. This was a problem for the topic bulk
actions because you couldn't append restricted tags to topics.

This commit allows restricted tags to be used in bulk tagging actions
as long as all selected topics are for a sole category. The category
information will be shown in the modal, and the category ID is used
for the tag search.
