fix(review): wire Deployment annotations and fix systemPrompt JSON

Two fixes from PR #1285 (ArgoCD) review feedback:

- deployment.yaml: add {{- with .Values.annotations }} block to Deployment
  metadata so reloader.stakater.com/auto: "true" (already set in global
  ArgoCD values) is actually applied. Without this the Stakater Reloader
  never sees the annotation and ConfigMap changes don't trigger a rolling
  restart.

- values.yaml: replace invalid JSON tokens (..., // comments) in the
  weeklyBriefPrompts.systemPrompt schema example with valid placeholder
  values and move cardinality rules to plain-text sentences. A model that
  copies the example now produces parseable JSON.
