Deploy sidekiq worker fix to production

[rileyseaburg]

Summary

Deploys the sidekiq worker fix from #1945 to production.

Critical Fix

The sidekiq worker has been crashing continuously because it was running rails server instead of bundle exec sidekiq. This fix adds the correct command to the deploy script.

Changes Included

• .circleci/deploy-sidekiq.sh: Added -c "bundle exec sidekiq -C config/sidekiq.yml" flag to cf push

Impact

• Fixes production sidekiq worker (currently showing 0/1 instances)
• Restores background job processing (exports, emails, scheduled tasks)
• Stops continuous "sidekiq worker failed" emails

Verification After Merge

cf app touchpoints-production-sidekiq-worker
# Should show instances: 1/1

cf logs touchpoints-production-sidekiq-worker --recent
# Should show Sidekiq startup messages

Fixes #1944
