This pull request introduces a recent searches feature across the application, allowing users to quickly access and reuse their previous search queries.

Recent Searches Feature Implementation:

• API and Backend Support:

  • Added new API endpoints and controller methods to get and save recent searches for authenticated users, including updates to the user model to store recent searches. [1] [2] [3] [4] [5]

• Search Bar Enhancements:

  • Updated SearchBar to display a dropdown of recent searches when focused and empty, support keyboard shortcuts (/ to focus, Escape to clear), and synchronize recent searches between localStorage and the server. [1] [2] [3] [4]

• Reusable Recent Searches UI Component:

  • Introduced a new RecentSearchesPanel component for displaying recent searches, which is now used in the Ask Question, Dashboard, and Query pages. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
