Sends persistent notifications to the HA dashboard using the existing
HA connection from Settings. Zero config — just select "Home Assistant"
as provider type. Users can forward notifications to mobile via HA
automations.
home_flag bit 18 was incorrectly interpreted as "wired/ethernet
connection", causing the ethernet badge to always show — even on
printers without an ethernet port (e.g. A1, P1S). This hid the
WiFi signal indicator entirely.
Removed the wired_network field and ethernet badge UI. The WiFi
signal badge now shows correctly whenever the printer reports
signal strength.
Nozzle rack id 0 = extruder 0 = right nozzle, id 1 = extruder 1 = left.
The dual-nozzle hover card had them backwards, showing serial number and
max temp on the left column instead of the right. Serial and max temp
are now restricted to the right (removable) nozzle only. Single-nozzle
fallback (H2D, H2C) updated to use the primary nozzle (id 0).
