When an existing LND wallet is locked and none of the candidate passwords
(per-node secret, legacy constant) open it, the node can never auto-unlock
unattended. unlock_existing_wallet now returns Ok(false) for "all candidates
actively rejected" (vs Err for transient "LND not ready"), and
ensure_wallet_initialized responds by recreating the wallet:
- mark the lnd container user-stopped so the health monitor won't
re-launch it (and re-open the wallet) mid-wipe,
- stop lnd, delete its wallet/chain/graph state as root,
- start lnd, wait for NON_EXISTING, re-init a fresh wallet on the
per-node secret, then clear the user-stopped flag.
LND runs as a plain bridge-network podman container (not a Quadlet unit),
so it is restarted via `systemd-run --user --scope podman`, matching the
orchestrator/health-monitor path.
Alpha nodes hold no funds and a wallet locked with an unknown password is
already inaccessible, so the wipe loses nothing reachable. Completes the
forward fix from 91adc281 for nodes whose wallet pre-dates the per-node
secret and whose password is unrecorded (e.g. .116/.228).
