Phase 2: toolbar responsive patterns

- All page toolbars now flex-wrap on mobile with min-h instead of fixed h-16
- Segmented button filters (priority, status, view) hidden on mobile, replaced
  with compact Select dropdowns
- Search inputs hidden on mobile where CategoryFilterBar already has search
- CategoryFilterBar wraps to full-width row on mobile (order-last)
- Action buttons show icon-only on mobile, full text on md+
- Calendar title hidden on xs screens for space
- Desktop layout completely unchanged (md:flex-nowrap restores original)
