Sorting buttons based on views or duration, option to display HD videos first

Always wanted the sorting feature in Thisvid and finally got around to do it! It will add an extra row in the current UI with three buttons. `HD First` button will preserve the current sorting logic. *I know I should've changed `defaultSchemeWithPrivateFilter` to be more graceful but quick and dirty also works some time 😛* <img width="1094" height="946" alt="CleanShot 2025-08-02 at 13 57 44@2x" src="https://github.com/user-attachments/assets/b52eaf6c-32d4-41bc-b47a-0513ab9ca03d" />
