- Create `USB_HOST_TYPE` base driver in TactilityKernel
- Refactor esp32_usbhost dts format, and create child devices dynamically
- Use PSRAM for task stacks where possible: saving 20 kB from just the task stacks, but roughly 30 kB when nothing is connected.
- Allow the user to disable USB host interface in the USB settings app, saving an additionaly 20 kB of IRAM when nothing was connected.
- Change listener-based APIs to subscribe and poll/await pattern. This avoids callstacks of apps and services leaking into the USB API
This results in big IRAM savings: 30 kB when USB host is on and nothing is connected, and 50 kB total when USB host is disabled.
This brings the total free IRAM after boot from roughly 170 kB to 200 kB (host enabled) or 220 kB (host disabled).
- Implement double size icon assets in `lvgl-module`
- `AppList` and `Settings` app now show a paginated grid of icons
- T-Lora Pager gets a larger font to improve readability (14 -> 16 pixels)
- Improve default widget selection in several apps (`PowerOff`, `AlertDialog`, `AppList`, `Settings`, `Boot`)
- USB HID LVGL device is now only created when necessary. And the code is called in a safer way.
- Renamed “Region & Language” to “Locale.”
- The terminal toolbar is shown only when pointer input is available.
