Vitja's Hopper(funnel)

Bug Fixes:
  - Fixed hoppers not functioning after server restart / world reload. Hoppers would occasionally stop ticking and
  appear "frozen" — placing a block nearby would wake them up again. Root cause: chunks loaded after the initial startup
   scan were not having their hopper ticking state re-enabled. Added a ChunkPreLoadProcessEvent handler that scans each
  newly loaded chunk for hoppers and restores their ticking state. Also fixed a race condition where onTick could return
   IGNORED before numeric IDs were resolved, permanently stopping the tick.
  - Fixed hoppers unable to push/pull items from multi-block containers (e.g. double chests). When a hopper targeted a
  sub-block (filler) position of a multi-block structure, it failed to find the container. Filler block resolution is
  now applied generically to all container lookups, not just processing benches.
