UI improvements: styling and layout fixes

- Prefill first store in shopping quick-add
- Tone down overdue/priority styling (red -> amber)
- Remove quick-add panel from tasks tab (use modal instead)
- Increase card opacity for better readability
- Swap task/event formatting (tasks get cards, events get border-l-4)
- Add grid layout for tasks (2-3 columns on wider screens)
