Add an always-on functional staging profile with 100m CPU requests for the app and ingress and 250m for PostgreSQL. Keep database isolation, volumes, memory, images, pools and replica bounds unchanged.
This commit enables the preparation phase on existing nodes. After workload verification, the enabled phase allows two e2-standard-2 nodes. The private saved-plan wrapper rejects replacements, unrelated changes, and node resizing before live reservations are prepared; temporarily uses database maintenance windows with PVC reuse during node updates and restores their prior values.
Validation: deployment Go tests and all 47 Python guard tests pass. Private staging preview required before merge; live verification remains required after each phase.
