fix: disable discord-bot and walava-web until images exist in registry

These custom images (discord-bot, walava-web) are built by their own
repos' CI/CD and pushed to git.walava.io registry. On a fresh server
Forgejo hasn't run yet so images don't exist — bootstrap chicken/egg.
Re-enable after Forgejo is up and images are pushed.
