Post-reboot audit PASS + night window extended to 22:00-07:00 (#610)

Verified after the 22:53 multiqueue bounce: NIC queues live at 4/4 and
2/2 (the whole point of the reboot), PVE config clean with nothing
pending, both gateway lanes healthy, all 9 Open Terminal ports bound on
the tailscale IP, PSI metrics fresh, and no removed relaunchers
respawned. Moved the day-profile flip from 05:00 to 07:00 per human
ruling (live timer re-armed + staged copy and docs synced; the gateway
z.ai peak ladder is untouched). Also staged a ready-to-run script that
drops each account's own Open Terminal key into its ~/.creds as
openwebui.creds - not run yet; the master key list stays at
~/.creds/open-terminal.env.
