feat: Add workflow inputs and Bicep infrastructure deployment

- Add workflow_dispatch inputs for azure_location (choice) and instance_number
- Add deploy-infrastructure job to deploy Bicep templates
- Calculate resource parameters from instance_number and location
- Use idempotent deployment name based on instance number only
- Configure ACR managed identity authentication

Closes #15
