feat: bypass reviews for deployment automation

[glitchedmob]

Splits review enforcement from baseline branch protection so deployment automation can merge staging promotions without human approval.

• Adds reusable review-only bypass actors to the repository module
• Grants the deployment automation GitHub App pull-request bypass access for infra-k8s-apps
• Keeps required Kubernetes checks, conversation resolution, and other branch protections non-bypassable
• Orders ruleset updates so approval enforcement remains active during apply
