Modernise the button "Notification" flow on page Home to improve performance.
I haven't moved the code from the Blueprint to ESPHome yet, as I will leave this for when we rebuild the Notification flow in the near future (hopefully), so the performance gains may not be perceived now. Just aligning with other buttons format.
* Create `nspanel_us_land.tft'
Add `nspanel_us_land.tft' for US panel on landscape mode, fixing the offset on the touch screen when using `nspanel_eu.tft` into a US panel.
Hides the hardware buttons labels, as Nextion cannot support rotated text.
