MultiCore Helper: Coffee Expansion

IMPORTANT: UPDATE REQUIRED

- Fixed coffee machine input/output interaction, including portafilter insertion, item removal, extraction start/stop, and queued brewing while heating.
- Reworked the coffee machine HUD: status and errors now use a dedicated panel; water, pressure, and extraction details no longer overlap slots or item tooltips.
- Added a functional placeable hand coffee grinder. Right-click it with roasted coffee beans to produce ground coffee.
- Added coffee grounds. Knock out a used portafilter by sneaking and right-clicking; coffee grounds can be used as fertilizer.
- Added operation-specific coffee-machine audio for grinding, tamping, portafilter handling, switches, espresso extraction, milk steaming, pressure release, rinsing, and knocking out grounds.
- Added water-bottle and water-bucket tank filling.
- Experience Coffee is now crafted from finished Coffee plus an Experience Bottle or Condensed Experience and is no longer produced directly by the machine.
- Fixed coffee machine models, collision, names, tooltips, JEI guidance, and recipe presentation.
