Battle Cache

## Fixed

- **Container reading is now a GUI action.** Pressing F8 while aiming at a chest, trapped chest, double chest, barrel, shulker box or modded container opens the config screen with a new **Read container** button. Clicking it reads that container on the server and appends its contents to the global loot pool; existing pool entries are kept and everything is saved when the screen closes. The previous implicit "F8 reads the aimed container" path has been removed.

- **Footer hint text no longer runs off the screen.** Hints are wrapped to the available screen width and shortened, on both the per-cache and global-pool tabs.

- **Naturally generated caches now open outward.** When a wild cache spawns flush against terrain (hillside, wall, tree…), the front/latch side is turned away from the blocking blocks instead of pointing into them.

- Config packets now touch the level and block entities on the server thread (`enqueueWork`) instead of the network thread, which makes container reads and pool saves reliable.
