Merge develop into main (#343)

- Refactor `AppManifest`: add new fields and rename existing ones
- Parse and validate the manifest from an app that is being installed.
- Remove deprecated `scoped()` from `Lock`
- Create `Tactility/Paths.h`
- App loading at boot now properly parses the manifest files of external apps
- Properly lock both source and destination locations during app install
- Remove LVGL path variants from `AppPaths` and `ServicePaths`
- Removed `xPath` base classes for apps and services. There's now `AppPaths` and `ServicePaths`.
- Renamed app and service paths: "data" and "system" paths are now "user data" and "assets"
