Update UI for Filter Bar and Bottom Bar

[NghiaTranUIT]

🐶 Brief

As from the following screenshot, the Filter Bar and bottom bar looks bad when the Content Panel overlap both. We should improve the UI to make it better.

👑 Criteria

• Make bottom Toolbar expand to right-edge (Flow List + Content Panel are above)
• Filter Bar should always be visible and position out fo Flowlist + Content panel
• Search View in Filter Bar should be hidden like Xcode (until hit CMD+F)

All done in Proxyman 1.8.0 🎉
