The Planning app code has been reorganized by moving separate planning classes into their own files. This does not change user-facing behavior, but it makes the codebase easier to maintain and safer to update in the future.

- split planning classes each to its own file

Task: 4866865

The IoT-related driver and homepage components were consolidated into a single module structure. This reduces internal complexity and helps keep maintenance of connected device features more consistent without changing day-to-day business workflows.

`hw_posbox_homepage` files had no reason to be placed in a separate module, we then merged it into `hw_drivers`, that we renamed `iot_drivers` in the meantime.
