- Removed all logic that read or set NAMESPACE/PROLE_NAMESPACE from the shell environment or wrote it to env.sh.
- prole.cfg is now the sole source of truth for the namespace value, loaded exclusively by prole_cfg.sh.
- etc/prole_cfg.sh & mock_val/prole_cfg.sh: Removed kubectl-context fallback and default for PROLE_NAMESPACE.
- Shell scripts (init_*.sh): Replaced NAMESPACE=${NAMESPACE:-...} with NAMESPACE="${PROLE_NAMESPACE}".
- Python (actions, environment, milestone): Removed env["PROLE_NAMESPACE"] from subprocess env dicts and env.sh.
- etc/init_cloudnative_pg.sh: Removed DB_PASSWORD env fallback for secret creation.
