Feature/enhance search

[bertearazvan]

What does it fix?

• It adds a county dropdown and filters the search results by the given county. Moreover, it renders the extended results underneath the search bar. If there is no search criteria, the user is being redirected to /asociatii.
• It also fixes the bug where the searchbar was not responsive on screen resize.
• I have primarily checked the mainpage and /asociatii as I haven't seen the searchbar on other pages. Otherwise, let me know 👍🏼

How has it been tested?

The app was tested locally and I have created a staging deployment with raw data on this link.
