Subject: [PATCH] REFACTOR(resources): remove cpu limits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- to prevent throttling
Removed CPU limits from all infrastructure components while keeping
memory limits for protection:

- cnpg: removed 500m CPU limit
- external-secrets: removed 200m, 100m CPU limits (operator, webhook,
  certController)
- falco: removed 500m CPU limit (falcosidekick webui)
- vault: removed 500m CPU limit
- velero: removed 500m, 1000m CPU limits (server, node-agent)

Benefits:
- ✅ Prevents CPU throttling
- ✅ Better performance and lower latency
- ✅ More efficient resource utilization
- ✅ Simpler management (only requests to tune)

Memory limits are kept to prevent memory leaks and OOM issues.
