feat: improve search history to show recently used tools with direct navigation

- Store feature keys (PageType) in history instead of translated labels
- Show icon + name + description in history items (same as search results)
- Click or Enter on history item navigates directly to the tool page
- Remove History icon import (no longer needed)
