✨ feat(deploy): chart Vault CRDs gated by vault.enabled (default false)

Adds VaultAuth + VaultStaticSecret + VaultDynamicSecret templates gated behind .Values.vault.enabled (default false). Default helm install keeps working in degraded mode. Chart becomes Vault-ready without activating Vault dependencies. iac/ terraform + Vault workflow follow as PR-IAC1 (requires user manual prereqs in Vault).
