Remove printer mixins; printer-side TakeItOutCompat handles the integration

[BiliXWhite]

The refactored litematica-printer (26.2+) now actively adapts to TakeItOut
through its own TakeItOutCompat in interfaces/compat/:

• ModuleManager.tick() calls TakeItOutCompat.isAwaitingItem() to
  block all module processing while a server-side extraction is pending
  → replaces the old NewPrinterMixin HEAD injection on
  ClientPlayerTickManager.tick() / ModuleManager.tick()

• InventoryUtils.switchToItems() calls TakeItOutCompat.tryExtract()
  as a last resort when the required item is not in the player's
  inventory and QuickShulker is unavailable
  → replaces the TAIL injection that manually scanned PrinterBox
  positions for shulker extractions

Since the printer side now fully drives the TakeItOut integration,
the TakeItOut-side NewPrinterMixin is entirely redundant and has
been removed.

Also, I fixed gradle's dependency request, which should not be hardcoded with "libs/".
