Add 'Add to feed' button on episode pages and fix typecheck.sh

- Episode pages now show 'Add to feed' button for logged-in users
who don't have the episode - Added POST /episode/{id}/add-to-feed
endpoint - Tracks 'added' metric when user adds episode to their feed -
Added Database.track_episode_metric() function for metrics tracking -
Fixed typecheck.sh to use bild instead of broken repl.sh approach
