Story

This PR makes three key updates:

1. Fix Go template evaluation error

   • Deployment was failing because the env var SERVERLESS_TEMPLATE was being evaluated as a Go template.
   • The value was:

     "{{dir_parts[-1..-1]}}/{{ basename }}{{ extension }}"

   • To prevent Go from interpreting it, the value is now wrapped in {{ }} to escape templating.

2. Update Redis Bitnami image

   • Switches to the latest available Bitnami Legacy Redis image:

     7.0.2-debian-11-r9
     

3. Align aux worker deploy with chart version 3.7.1

   • Updates the startup script used by aux worker.
   • db-wait.sh is replaced with service-wait.sh to match changes introduced in chart 3.7.1.
