fix(dbaas,actualbudget): apply OOM fixes — sync live cluster with Terraform code

Live cluster had stale resource limits causing OOMKills:
- actualbudget-http-api: 128Mi → 512Mi (code already correct)
- pg-cluster CNPG: 512Mi → 4Gi (code already correct)
- dbaas ResourceQuota: 20Gi → 24Gi live (TF code has 64Gi)

Formatting cleanup from terraform fmt included.
