[FIX] web,base: correctly display activity widget in partner kanban view

Revision on 7ecae33571

Commit above introduced activity widget on partner kanban, but
unintentionally affected style of all other kanban views that have
details on kanban record.

This commit fixes the issue by applying special CSS rule only on
partner kanban view, so that other kanban views remain unaffected.
