- LVGL image cache 512KB + header cache 16 on PSRAM (was PNG bottleneck, c4ec7ead)
- DisplaySettings.disableScreensaverWhenCharging persisted, checked via PowerDevice::IsCharging
- Display app: 'Disable on charging' toggle under Display settings, auto-disabled when timeout off
- DisplayIdle: skip screensaver while charging, auto-stop if plugging in while dimmed
- Keeps upstream full-DTS board clean, no JPEG decoder, no BT HID combo per user
