The IoT Box now downloads drivers and interfaces only from installed modules, plus the core base handlers. This reduces unnecessary background activity, improves performance, and avoids showing irrelevant drivers to users.

Previously, all drivers and interfaces found on the server were
downloaded to the IoT Box. Having unused interfaces and drivers on the
IoT Box slowed it down as threads were running for nothing.

It was also confusing for some users to see those drivers on the IoT
Box homepage (e.g. SerialBlackBoxDriver when located outside of
Belgium)

We now download only the handlers from installed modules + the base
handlers located in hw_drivers.

Improve the onboarding of new users and clean a few screens.

This update aligns email themes, barcode screens, and Studio report editing with a new background color naming system. It helps keep visual styling consistent and prevents layout checks from being confused by the renamed color classes.
