Add search history and recent searches dropdown #14
Description
Users who return to the site have to retype searches from scratch. A recent searches dropdown would speed up repeat visits.
Proposed solution
Store the last 5 searches in localStorage and show them as suggestions when the search bar is focused but empty.
Acceptance criteria
- Recent searches shown when search bar focused with empty input
- Clicking a suggestion populates and runs the search
- Clearable from the UI
- Capped at 5 entries, oldest dropped first
