Replace shortcuts dropdown with shorter button labels

Convert the shortcuts dropdown menu to individual buttons with concise text:
- 'No reviewers' (was 'Patches with no reviewers')
- 'My patches' (was 'Patches where you are author')
- 'My reviews' (was 'Patches where you are reviewer')

This makes the shortcuts more immediately visible and saves space.
