Nivona brew-override improvements, ported from community testing on real NICR hardware.
Added
- Brew Water Amount override for Nivona. A new
water_amountslider (0–240 mL, default 100) joins the existing strength / coffee-amount / temperature / milk-amount overrides. The field was already supported by the temp-recipe write path; it is now exposed as an entity. - Reset Brew Overrides button for Nivona. Clears the
user_setflag on every override slider and restores defaults, so the next brew uses the machine's own saved recipe instead of a temp-recipe override.
Fixed
- Partial temp-recipe writes brewed wrong amounts on Nivona. When any override slider was set, only the changed fields were written, and the firmware filled the omitted fields with hardware defaults (not the saved-recipe values) — silently brewing wrong amounts for the untouched fields. Brew overrides are now all-or-nothing: setting any slider sends the complete set of current slider values; setting none leaves the saved recipe untouched.
