RLCD ST7305 has !supportsBacklightDuty(). Previous fix that fixed MCP flash-then-back left entire idle state machine gated by supportsBacklight, causing once dimmed it could never wake on button press -> appears locked weird state reported.
Fix: run timeout logic for all displays, guard only setBacklightDuty calls.
- timeout disabled (Never) branch always restores displayDimmed
- timeout activation creates screensaver for all
- wake on inactive<100ms + charging block works for RLCD
- setBacklightDuty only when supportsBacklight && display!=nullptr
Also preserves deadlock-free ordering (MCP state outside LVGL lock) from 3629ffef.
