delete picks

Users should be able to swipe picks and delete them. Internally:
- we delete them from the picks object
- we log in the picks object deleted picks
- these are filtered out during the pick-ing process.

Look for the picks object and the swipe interaction in the mobile frontend code. Identify where picks are rendered and how swipe gestures are handled. Check for existing deletion logic and logging. The feature involves updating the UI to allow swiping, modifying the picks object to delete and log, and ensuring deleted picks are filtered during the pick-ing process.
