Fix permissions UX issues with data directories (#538)

* Try to make `pi` user owner of data & logs directories

* Try to run the hardware controller service as the `pi` user

* Also set `pi` for group ownership

* Bump device-backend

* Try to simplify setup of dirs needed by device-backend

* Bump hardware controller & pallet-standard for merged PRs

 - (System: networking) `planktoscope.local` and `pkscope.local` should now work on local area networks (i.e. when the PlanktoScope is connected to a router) and not just on direct connections.
 - (Application: GUI) The Node-RED dashboard's sample page's "Dilution Factor" input field has been renamed to "Concentration Factor", which is a less misleading name for what that input field actually represents.
+- (Application) The `/home/pi/data` and `/home/pi/device-backend-logs` are now created with non-`root` user ownership, so that their contents can be managed via an SFTP/SCP connection as the `pi` user. This fixes a regression introduced with v2023.9.0-beta.0.
