pack: correct Numismatics coin IDs (5 denominations, not 4)

The 0.18.0 economy_policy.js named 'numismatics:sundial' which doesn't
exist -- the real registry IDs are spur, bevel, cog, crown, sun. The
KubeJS warning surfaced this at startup:

  Failed to read ingredient from numismatics:sundial:
  Item with ID numismatics:sundial does not exist!

Updates both economy_policy.js (recipe removal) and jei_hides.js (JEI
hide) to use the correct 5-denomination list. Bumps to 0.18.1.
