Fix facet pills replacing body instead of self on HTMX update

Add hx_target="this" to the dsl_facet_pills container to prevent HTMX
from inheriting hx_target="body" from the parent wrapper. Without this,
clicking a facet pill would cause the facet refresh to replace the entire
body with just the pills HTML, breaking forms on pages like /actions/outcome.
