REWOLF CUBE 3.0 — KUBEJS V2.1 FIX

Solar Flux Reborn 21.1.8 was inspected directly.

Important correction:
Solar Flux registers its recipes dynamically through HammerLib.
The panel recipe IDs are:
  solarflux:solar_panel_1 ... solarflux:solar_panel_8
while the panel item/output IDs are:
  solarflux:sp_1 ... solarflux:sp_8

V2.1 removes BOTH the native recipe ID and every SP1-SP8 output recipe
before adding the Rewolf replacement recipe. This prevents the vanilla/native
Solar Flux panel crafts from remaining beside the Rewolf crafts in JEI.

Mechanical Extruder changes from V2 are preserved.

Install:
1. Back up kubejs.
2. Replace the existing kubejs folder/scripts with this V2.1 package.
3. Fully restart the server (recommended rather than relying only on /reload).
4. Check SP1-SP8 in JEI. Each tier should show the Rewolf recipe only.
