- Implement ST7305 driver at `Drivers/st7305-module` - Rename `cl32` device project to `cl32-v02-v03` and removed v0.4 drivers - Implement CL-32 v0.4 device as `cl32-v04`: display, keyboard, backlight/frontlight driver and power supply - Remove `TT_LAUNCHER_APP_ID` (it was always the same setting) - Remove `TT_LVGL_STATUSBAR_COLORS_INVERTED` (unused since recent changes) - Wi-Fi only refreshes once, so users can navigate with the keyboard through the results, without constently resetting focus/selection. After initial scan, manual scans can be requested via the toolbar. - Themes: material and material_mono theme don't show post-selection border animation anymore. It looks weird on monochrome devices and it doesn't add anything on other devices either. - Made `merge.sh` executable - backlight driver API change: min/max brightness functions are now optional, defaults to [0, 255]
