feat: convert services to new install script template

[rackerchris]

Feature:Refactor Service Installation Scripts to Use Standard Template

This PR updates all services install/upgrade script to conform to the standard bash template.
Key Changes & Benefits:

• Standardization: Adopts the robust, array-based command construction (helm_command) for safer execution and argument quoting.
• Dynamic Values Loading: Switches to the standard loop logic for reliably including all .yaml files from both the base and custom override directories (/opt/genestack/base-helm-configs/redis-sentinel and /etc/genestack/helm-configs/redis-sentinel).
• Improved Reliability: Ensures consistent extraction of the service chart version using the defined SERVICE_NAME variable.
• GITHUB ACTIONS: Ensures that a github action exists for each service for pre-commit checking

This change reduces technical debt and makes the script easier to audit and maintain.
