Change application/version setting source to remove redundancy

This change remaps some settings
It removes `xr/tilt_five/application_id` and uses  `application/config/name` instead.
It removes `xr/tilt_five/application_version` and uses `application/config/version` instead.

This change is in alignment with the intended use of these fields for identifying the application in the T5 service logging.

Additionally if `xr/tilt_five/default_display_name` does not have a supplied value `application/config/name` is used.
