feat(provazio): Add serviceAccount.annotations support for IRSA

- Add annotations support to dashboard-service-account.yaml template
- Add annotations support to vault-service-account.yaml template
- Add serviceAccount.annotations to values.yaml for dashboard and vault

This allows IRSA (IAM Roles for Service Accounts) annotations to be
configured via Helm values, ensuring they persist across helm
install/upgrade cycles.

Example usage:
  dashboard:
    serviceAccount:
      annotations:
        eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/my-role
