[BUG] Add fallback for bUp Navigation without History

[ClaireRovic]

PROBLEM DESCRIPTION

When using the defaultCard to point to a HiddenCards, the navigation arrows will not let me move back up through the menu system. I use this to set the NSPanel default for different rooms in the house depending on where the panel is located. At the top level of the menu I have all the rooms that can be selected.

The default card cannot point to a hiddencard, as described in the docs.

default page after exiting screensaver; only works with top level cards defined in cards;

https://docs.nspanel.pky.eu/config-screensaver/?h=screensaver#possible-configuration-values-for-screensaver-config

However it might be possible to add a fallback to point it to the first card in case it doesn't find one on exiting a hidden card.

[ClaireRovic]

Thanks for the fast feedback - apologies I have read the docs, just not everything sticks. The fallback option sounds like a sensible approach in the event of other unforeseen issues. Smile plus it will solve my problem 😂

[joBr99]

Hey checkout the development version, you only need to update to main in HACS and restart AppDaemon, Firmware is not required.

https://docs.nspanel.pky.eu/faq/#how-to-upgrade-from-a-release-to-the-current-development-version

If there is no card found to go up, it is no going to the first page.
