Add template name / target VPD to main overview screen

In the main preview screen, include the name of the current Notifications template.

The growing process require us to move from week to week and change the template of the notifications. The template name itself is informative of the stage the specific room is in. It would be nice to be able see this info as I check the main overview.

For example my templates names read: Late flower VPD 1.5, or Seedlings VPD 0.6. This is very relevant info for the preview screen of all devices. If you have 6 different rooms as in my case it it also good to see which notification template is loaded.

Target VPD could be also visble as a separate field for the same reason. In my case I have included it in the name.

This is also a safety measure in case you have the wrong template loaded. An insurance.
