Merge develop into main (#312)

- Move various settings to `/data/settings` and `/sdcard/settings`
- Fix for `Gui` and `Statusbar` errors on startup (LVGL start)
- Implement Development service settings as properties file
- Rename `service::findManifestId()` to `service::findManifestById()`
- Renamed various classes like `BootProperties` to `BootSettings`
- Renamed `settings.properties` to `system.properties`. Code was moved to `settings` namespace/folder
- `DevelopmentSettings` is now in `settings` namespace/folder (moved from service)
