Detailed Description

Power sub-menu on a single screen: sleep delay, auto power-off, and power off.

One screen split into three vertical zones; UP/DOWN moves the focus between them:

• Sleep : horizontal preset picker (LEFT/RIGHT cycles, wrapping) for the screen sleep delay.
• Auto off : same, for the auto power-off delay.
• Power off: a centred button. SELECT opens a confirmation popup with Confirm/Cancel.

The two idle timeouts are persisted through the power service on BACK, only if they actually moved (Rule 13: no NVS write per scroll step).

Power-off is gated on external power: SELECT on Confirm releases EnableReg and cuts the rail (power_shutdown() never returns). The rail is also latched on by USB, so shutting down while USB is connected would spin power_shutdown() forever – when USB is present the popup shows a warning and refuses instead of walking into that dead end.
