Fix mobile layout for iPhone-sized viewports

- Stack header vertically on mobile (flex-col sm:flex-row) to prevent logo+nav overflow
- Hide venue and price columns in list/row views on mobile to give title room
- Shrink date/time columns on mobile (w-24 sm:w-32, w-20 sm:w-28)
- Make keyword filter input full-width on mobile (w-full sm:w-52)
